[0001] 本申请基于并要求2010年6月30日提交的美国临时申请No. =61/359,875的优先权,该临时申请通过引用包括在此。 [0001] This application is based upon and claims the United States June 30, 2010 filed Provisional Application No. = 61 / 359,875, filed in the provisional application by reference herein.

技术领域 Technical Field

[0002] 本发明涉及一种井下装置、一种在井下分离流体和固体的方法以及一种配备井下流体和固体分离系统的方法。 [0002] The present invention relates to a downhole apparatus for separating fluids and solids in downhole method and a method with downhole fluids and solids separation system.

背景技术 Background

[0003] 油井生产可涉及泵送包含部分油和部分水、即作为油/水混合物的井流体。 [0003] Production wells may involve the pumping of oil and part of the water containing portion, i.e., as an oil well fluids / water mixture. 当油井的油衰竭时,具有更大百分比的水,且随后被生产到地面。 When oil wells failure, with a greater percentage of water, and subsequently produce to the ground. “生产”的水有时可达到生产出的总的井流体体积的80%以上,从而产生严重的操作问题。 "Production" of water can sometimes be more than 80% of the total production of the well fluid volume, resulting in severe operational problems. 例如,生产出的水可能需要处理和/或再注入地下储层中,以处置水和帮助保持储层压力。 For example, to produce the water may require treatment and / or re-injected into underground reservoirs, in order to dispose of the water and help maintain reservoir pressure. 生产出的水的处理和处置花费 Treatment and disposal of produced water cost

很1¾。 It 1¾.

[0004] 一种应对这些问题的方式是,通过采用井下装置分离油和水,并将分理出的水再次注入,从而减少了生产到地面的不希望的水。 [0004] A way to deal with these problems is through the use of downhole oil and water separation apparatus, and the sub-sort of injection water again, to thereby reduce the production of undesirable ground water. 降低生产到地面的水可使得降低所需的功率,降低液压损失和简化地面设备。 Reduce production to reduce ground water such that the power required to reduce hydraulic losses and to simplify ground equipment. 而且,许多与水处理有关的成本可减少或省去。 Moreover, many of the costs associated with water treatment can be reduced or eliminated.

[0005] 然而,成功地在井下分离油和水、然后再注入水是相当棘手的,且是一种具有许多影响这种操作的效率和可行性的变量和因素的敏感过程。 [0005] However, the successful separation of oil and water in the pit, and then injected into the water is quite tricky, and is having a lot of sensitive processes affect the efficiency and feasibility of such an operation variables and factors. 例如,各个井的油/水比率可不同,且可随着井的寿命而明显地变化。 For example, each well of the oil / water ratio may be different, and may vary with the life of the well and significantly changes. 所需的注入压力也可随着井的寿命而变化。 The required injection pressure may also vary with the life of the well. 例如,分离出的水所需的注入压力往往随着时间而增大。 For example, the separated water injection pressure is often required to increase over time.

[0006] 当井流体包括有时混合在井流体中的固体、例如沙和其他颗粒时,会出现另外的问题。 [0006] When the well fluid comprises solid sometimes mixed fluid in the well, such as when sand and other particles, there will be another problem. 固体往往比油重,且从水析出。 Solid often than heavy oil, and precipitated from water. 然而,水流中的固体的存在可产生复杂的井下状况, 例如阻塞。 However, in the presence of water may produce solid complex downhole conditions, such as blocking. 在一些应用场合中,固体与被再次注入的水流分离且往往阻塞再次注入的位置。 In some applications, the solid was injected again with water and separated again tend to clog the injection position. 井流体/水中的固体比例也可随着时间变化,这在井下处理固体时会产生更大的困难。 Well fluid / solid ratio of water may also change over time, which leads to greater difficulties in the underground disposal of solid.

发明内容 DISCLOSURE

[0007] 总体而言,井下油-水-固体分离的多个方面提供了一种用于在井下分离流体和固体和处理已被分离出的固体的系统和方法。 [0007] Overall, downhole oil - water - many aspects of solid separation provide a system and method for separating fluids and solids and processing have been separated solids in underground. 该技术方案利用具有分离器的分离系统,所述分离器具有井流体入口、油流输出通道、水流输出通道和固体输出通道。 The technical solution using a separation system having a separator, the separator having a fluid inlet wells, oil flow output channel, output channel and solids output flow channels. 分离器用于将井流体大致分离成油、水和固体组分,且这些组分被引导到相应的通道。 Separator means for separating the well fluid into a generally oil, water and solid components, and these components are guided to the corresponding channel. 限流器可与分离器配合使用,以便于分离井流体组分。 Flow restrictor may be used in conjunction with the separator in order to separate the well fluid component.

[0021] 在此描述的实施例通常涉及机械采油系统,例如,与油气井相关的机械采油系统。 [0021] The embodiments described herein generally relates to mechanical extraction system, for example, oil and gas wells and related machinery production systems. 所述实施例包括用于分离井流体组分,例如油、水和固体的系统和方法。 The embodiment comprises, for example, a system and method for separating a fluid component of oil wells, water and solids. 例如,一个实施例涉及井下油/水/固体分离以及涉及管控用于操控井流体组分分离的背压。 For example, one embodiment relates to downhole oil / water / solids separation and relates to a control for manipulating the well fluid component separation backpressure. 一种控制油和水的分离的方式例如通过调节施加给油流和/或水流的背压进行。 A method of controlling the way the separation of oil and water, for example, to the oil flow and / or flow back pressure applied by adjusting. 背压可通过调节限流控制,以实现对退出井流体组分分离器的油流和/或水流的期望节流。 Backpressure flow control to limit by regulation, in order to achieve the well fluid component separator exit flow of oil and / or current expectations of the throttle. 除了井流体组分分离以外,在此描述的实施例涉及被设计用于向输出流提供期望节流、即背压的设备。 In addition to the well fluid component separation, the embodiments described herein relates to a throttle is designed to provide the desired output stream, i.e., the back pressure device. 节流幅度可根据井流体的油/水/固体含量在完全关闭(没有流动)到宽开口(充分流动)之间变化。 Well fluids according to the magnitude of the throttle of the oil / water / solids content is fully closed (no flow) to the width of the opening (full flow) varies between.

[0022] 控制背压和相关流动可与注水区相对于生产区(生产区的井上或井下方向的注水区)的方位高度地相关。 [0022] and related flow control back pressure injection zone with respect to the production area (or underground injection zone Inoue direction of production areas) orientation highly relevant. 这两个方位之间的一些差别涉及井上注入(injecting uphole) 和井下注入(injecting downhole),在所述井上注入中,装置可以单一操作节流和通到油管环空,在所述井下注入中,装置可能需要对流动“在线”节流,即,需要从油管接收注入流, 对该流进行节流,然后将该流返回到向着注水区行进的另一油管。 Some differences between these two orientations involves Inoue injection (injecting uphole) and downhole injection (injecting downhole), said Inoue injection, the device can operate the throttle and passed to single tubing annulus in the downhole injection in the device may need to flow "online" throttling, namely, the need to receive the stream injected from the pipe, the flow restrictor, and then flow back to the other injection zone traveling toward pipeline. 在一些应用中,限流器的节流通道/或开口的直径可在大约0. 125英寸到1. 0英寸的范围内。 In some applications, the flow restrictor throttle channel / or openings have a diameter in the range of about 0.125 inches to 1.0 inches of.

[0023] 总体上请参看图1,井系统20被示为部署在井眼22中。 [0023] In general see Figure 1, the well system 20 is shown deployed in a wellbore 22. 在该实施例中,井系统20包括潜入式电力泵送系统对,所述潜入式电力泵送系统M具有潜入式马达26和由潜入式马达沈驱动的潜入式泵28。 In this embodiment, the well system 20 includes a submersible pumping systems power the submersible pumping system M has the power submersible motor 26 and by a submersible motor-driven submersible pump sink 28. 潜入式电力泵送系统M可包括多种其他构件、例如泵开口或进入口30和马达保护器32。 Power submerged pumping system M may include various other components, such as a pump or inlet port opening 30 and a motor protector 32. 附加性地,示出的井系统20还包括被设计成用于分离井流体组分的分离器34,例如离心分离器或旋流分离器。 Additionally, the illustrated well system 20 further includes a separator designed for separating the components of the well fluid 34, such as a centrifugal separator or cyclone separator. 例如,分离器34可被设计成用于分离流体组分、例如油和水,流体和固体组分、例如水和颗粒,或其他组分组合、例如油、水和固体。 For example, separator 34 may be designed to separate fluid component, such as water, fluid and solid components, such as water and particulates, or other combinations of oil components, such as oil, water and solids. 分离器34可在多种位置、例如在示出的潜入式泵观上方的位置连接到井系统20中。 Separator 34 in a variety of locations, such as in the position shown above concept submersible pump connected to the well system 20. 然而, 分离器34还可定位在潜入式泵观的上游,以限制固体流过泵观。 However, the separator 34 may also be positioned upstream of the submersible pump concept, in order to limit the flow of solids through the pump concept.

[0024] 在示出的示例中,井系统20放置在油气井的井下,例如井的套管36内。 [0024] In the example shown, the well system 20 is placed in the underground oil and gas wells, such as well casing 36. 当放置在井下期望位置处时,潜入式马达26可供给动力,以驱动潜入式泵观和分离器34。 When the desired position is placed in the underground, submerged motor 26 can supply power to drive submersible pump concept and the separator 34. 在该实施例的操作过程中,井流体通过开口30被吸入泵观中且被泵送到分离器34中。 In operation of the embodiment, the well fluid is drawn into the pump through the opening 30 and is pumped to the concept of the separator 34. 分离器34加速并沿圆形路径驱动井流体混合物,从而,利用离心力将密度较大的物质、例如水和固体定位到更远的径向位置,以及将密度较小的流体、例如油定位到与转动中心更接近的位置。 Separator 34 along a circular path and to accelerate the drive shaft of a fluid mixture, so that, by centrifugal force denser substances, such as water and solid positioning farther radial position, and the less dense fluid, such as oil to locate closer to the center of rotation of the position. 在该示例中,油流和水流从分离器34排出并沿着不同的路径单独地行进到方向改变装置38, 所述方向改变装置改变水流的方向,并将水流注入周围地层中,同时例如通过油管40将油流向井上引导到地面收集位置。 In this example, the oil flow and water flow 34 is discharged from the separator and separately along different paths to travel direction changing means 38, the direction changing means to change the direction of flow, and the injection water surrounding formation, e.g., by simultaneously The oil flow to the well tubing 40 into the ground to guide the collection position. 分离器34可被设计成用于分离油、水和固体(参看图10), 在这种情况下,井流体的固体组分被方向改变装置38引导到期望位置。 Separator 34 may be designed for the separation of oil, water and solids (see FIG. 10), in this case, the solid component of the well fluid direction changing means 38 is guided to the desired location. 应当指出,分离器34也可在具有或没有方向改变装置38的情况下用于多种位置。 It should be noted that the separator 34 may be with or without direction changing device 38 for the case of a variety of positions. 例如,分离器34可用于分离油、水和固体组分,然后再将固体与油流组合以给送到期望的地面收集位置,从而,避免堵塞注水区。 For example, separator 34 can be used to separate oil, water and solid components, then combined in a solid and the oil flow to the ground to collect the desired position, and thus, avoid plugging water injection zone.

[0025] 关于水流、油流和/或固体流,从分离器34的输出是指分别大致具有水、油和固体的浓度的流。 [0025] On the water, the oil flow and / or solid stream output from the separator 34 refers generally have water, oil and solids concentration stream respectively. 换言之,相应的流可包含一部分其他井流体组分,不可能是纯的而仅包含水、 油或固体。 In other words, the corresponding portion of the stream may contain other components of well fluids, which can not only contains pure water, oil or a solid. 根据特定的应用场合,井系统20可包括其他各种构件,例如封隔器42和44。 Depending on the particular application, the well system 20 may include various other components, such as the packer 42, and 44.

[0026] 图2示出了分离器34的一个示例的剖视图,在这种情况下,所述分离器是离心式分离器。 [0026] FIG. 2 shows a cross-sectional view of an example of a separator 34, in this case, the separator is a centrifugal separator. 井流体混合物被驱动通过分离器34的井流体入口45并进入分离器部分或分离器34的腔室46、例如旋流腔室中。 Well fluid mixture is driven well fluids through the separator inlet 34 into the separator 45 and the separator 34 or the portion of the chamber 46, such as cyclone chamber. 井流体的组分通过分流器48分离,所述分流器48限定出用于从分离器部分46运送已被分离的井流体组分的管道或通道。 Components of well fluids through the separator splitter 48, the diverter 48 defining a well for the fluid component has been separated from the separator portion 46 of conveyance duct or channel. 例如,通道可包括充当分离器腔室46的出口的油通道或管道50和水通道或管道52。 For example, the channels may include acts as a separator chamber outlet 46 of the oil passage 50 and the water channel or conduit or pipe 52. 分流器48还可从井流体分离出另外的组分,例如固体,所述固体沿着单独的固体通道或管道传送。 Splitter 48 may be separated from the other components of the well fluid, such as a solid, the solid along a separate channel or conduit conveying solid. 如图所示,油通道50 相对于水通道52在径向方向上偏内设置。 As shown, the oil passage 50 with respect to the water passage 52 disposed within the offset in the radial direction. 背压可选择性地施加给油流、水流和/或固体流, 以影响分离过程。 Backpressure can be selectively applied to the flow of oil, water and / or solid stream to effect separation process. 例如,当分流具有高百分比的油的井流体时,通过水通道52作用于水流的背压可改善分离结果。 For example, when the well fluid shunt with a high percentage of oil, by the action of water channel 52 to flow back pressure can improve separation results. 对于具有较高百分比的水的井流体,通过油通道50作用于油流的较高的背压可类似地改善油和水的分离。 For the well fluid has a higher percentage of water, a higher back pressure through the oil passage 50 acts on the oil flow could similarly improve the separation of oil and water. 总体上,相同的背压原理适用于旋流或离心式分离器。 In general, the same principles apply to the back pressure cyclone or centrifugal separator. [0027] 总体上参看图3,示出了另一类型的分离系统M的剖视图,所述分离系统具有分离器34,该分离器用于将井流体组分分成例如流过油通道50和水通道52的流。 [0027] Referring to Figure 3 in general, there is shown a cross-sectional view of another type of separation system M, the separation system 34 having a separator, the separator for the well fluid component into e.g. oil passage 50 and flows through the water passage stream 52. 应当指出, 分离器34也可设计成分离出固体组分,所述固体组分然后沿着单独的管道输送,这将在下面进行更详细的描述。 It should be noted that, the separator 34 can also be designed to separate the solid component, said solid component then separate along the pipeline, which will be described in more detail below. 在图3中,箭头56示出了表示油流的路径,箭头58示出了表示水流的路径。 In Figure 3, the arrow 56 shows the path of the oil flow indicating arrow 58 shows the flow path represented. 在该示例中,限流器60、例如节流构件定位在水通道52中。 In this example, the flow restrictor 60, e.g., the throttle member 52 is positioned in the water channel. 然而,替代性地,限流器60也可放置在油通道50中,或另外的限流器60可放置在油通道50中而使得在水通道和油通道中均具有限流器。 However, alternatively, the flow restrictor 60 can also be placed in the oil passage 50, or another flow restrictor 60 may be placed in the oil passage 50 and makes the water channel and the oil passages have restrictor. 在该实施例中,水流58向井上流入限流器60中。 In this embodiment, the water flows into the well 58 to flow restrictor 60.

[0028] 限流器60可以从多种不同类型的限流器中选择,其中一个示例具有节流孔件62, 所述节流孔件具有通流节流孔或通道64。 [0028] The flow restrictor 60 can choose from a variety of different types of flow restrictors, one example has an orifice 62, the orifice member has a through-flow orifice or channel 64. 节流孔64的尺寸可以变化,且限流器60和节流孔件62的结构使得能够调节水流58中的背压。 The size of the orifice 64 can be varied, and the limiting member 60 and the orifice 62 of the structure 58 makes it possible to regulate the flow of back pressure. 例如,限流器60可以是可移除的限流器,以便能被更换为具有不同的节流性能的其他限流器60,例如具有尺寸不同的通流节流孔64 的不同的节流孔件62,从而,能够调节背压。 For example, the flow restrictor 60 may be a current limiter can be removed in order to be replaced by other current-limiting device 60 having different throttling properties, such as having different dimensions different through-flow orifice throttle 64 hole 62, whereby the back pressure can be adjusted. 在其他实施例中,节流孔件62可移除,且可更换为具有尺寸不同的节流孔64的其他节流孔件62。 In other embodiments, the orifice member 62 may be removed and may be replaced with another orifice having a different orifice size of 62 64. 限流器60和/或节流孔件62可借助于工具66更换,所述工具可下放到井下,以放置和/或移除限流器60或节流孔件62。 The flow restrictor 60 and / or orifice 62 by means of the tool 66 replace the decentralized downhole tool to place and / or removal of the flow restrictor orifice 60 or 62. 作为示例,用于更换装置的工具可以包括在电缆、钢丝(slick line)、连续油管或其他合适的传送装置68上运行的工具。 As an example, the tool may comprise means for replacement of the tool on the cable, the wire (slick line), coiled tubing, or other suitable conveying means 68 to run. 在一些应用场合下,钢丝可以是用于改变节流特性的最经济的传送装置。 In some applications, the wire may be changing throttle characteristics transfer means for the most economical. 在图3中示出的示例中,油管道50可被定位或构造成防止由传送装置68下放的工具意外地进入油通道50中。 In the example shown in Figure 3, the oil conduit 50 can be positioned or configured to prevent the transfer means 68 decentralized tool accidentally into the oil passage 50. 例如,油通道50可具有倾斜部分70,以防止工具66进入管道中,或管道的尺寸可被选择成使工具66不能进入通道中。 For example, the oil passage 50 may have inclined portions 70, 66 to prevent the size of the tool into the pipe, or the pipe may be selected so that the tool 66 can not enter the passage.

[0029] 在一些应用场合下,限流器60包括节流孔件62,所述节流孔件62具有尺寸可变的节流孔64,使得不需更换限流器60来改变节流孔64的尺寸。 [0029] In some applications, the flow restrictor 60 comprises orifice 62, 62 having a variable size orifice of the orifice member 64, so that the need to replace the current limiter 60 to change the orifice size 64. 作为示例,节流孔的尺寸可在地面以机械方式调节,或通过经由传送装置68例如电缆、钢丝、连续油管下放的工具66进行。 As an example, the size of the orifice in the ground may be adjusted mechanically or via transmission means 68 such as cables, wires, coiled tubing 66 decentralized tool. 在其他应用中,节流孔件62可具有可调节的节流孔64,所述可调节的节流孔64可通过液压管路经由引到井下的液压调节或通过电机调节,所述电机通过从地面或从井下控制器发送的电信号控制。 In other applications, the orifice member 62 may have an adjustable orifice 64, the orifice hydraulic adjustable via hydraulic line 64 may be diverted to the by regulation or by a downhole motor, said motor by from the ground or the electrical signal sent from the downhole controller.

[0030] 如图3进一步所示,止回阀72位于油通道50和/或水通道52中。 [0030] As further shown in FIG. 3, the check valve 72 is located in the oil passage 50 and / or the water passage 52. 止回阀72可用于防止流体通过油通道50和水通道52移回分离器34中。 Check valve 72 may be used to prevent the fluid passage 50 through the oil passage 52 and water separator 34 moves back. 利用止回阀72阻止该可能的回流防止损坏分离器34。 The use of the check valve 72 prevents the backflow preventer may damage the separator 34.

[0031] 再次参看图1,封隔器42、44可用于沿着井系统20隔离井眼的多个区域。 [0031] Referring to Figure 1 again, the packer 42, 44 can be used to isolate the system 20 along the well borehole a plurality of regions. 作为示例,封隔器42和44被示为将水要再次注入到与方向改变装置38接近的地层中的区域与井流体从下封隔器44下方的地层抽吸的区域隔离。 As an example, the packer 42 and 44 are shown as the water to be injected into the direction change region and the well fluid 38 near the formation of isolation from the formation below the lower packer 44 suction the area again. 封隔器结构有效地将泵进入口30与再次注入的流体隔离。 Packer structure effectively pump inlet port 30 and again injected fluid isolation. 可选地,在水再次在封隔器42上方或封隔器44下方注入时,封隔器44可位于潜入式泵观下方,从而,充分地将生产出井流体的区域与水注入的地层的区域隔离。 Alternatively, in the water again in the bottom 42 above the packer or packer 44 injection packer 44 may be located below the submersible pump concept, whereby the region will be fully produced with water injection wells in fluid formations regional isolation. 可使用多种封隔器结构,只要它们被定位成在生产出的流体与注入的流体之间产生隔离即可。 Packer can use a variety of structures, so long as they are positioned between the produced fluid and injected fluid to produce isolation.

[0032] 井系统20也可被构造成能够向井下注入增产处理流体。 [0032] Well system 20 may also be configured to enable stimulation fluid injection downhole. 例如,在图4示出的实施例中,分离系统M与图3的分离系统类似,但限流器60已被移除。 For example, in Figure 4 shows an embodiment, the separation system M separation system similar to FIG. 3, but the flow restrictor 60 has been removed. 在图4的结构中,增产处理流体可沿着油管40向下泵送到油通道50和水通道52中。 In the structure of FIG. 4, stimulation fluid can be sent along the tubing 40 down pump oil passage 50 and the water channel 52. 限流器60可被更换为防止处理流体沿着再次注入的水的路径流动的流动装置。 The flow restrictor 60 may be replaced to prevent the process fluid flow device along the path of water flowing again injected. 作为示例,箭头74示出了表示增产处理流体的路径。 As an example, the arrow 74 shows the path of the fluid representation stimulation. 止回阀72防止增产流体行进到分离器34中,以避免对分离器造成有害作用。 Check valve 72 prevents the fluid travels to the increase in the separator 34, the separator in order to avoid harmful effects.

[0033] 总体上参看图5,示出了一种替代性结构,以显示将水流再次注入到位于生产区78下方的期望注水区76。 [0033] Referring generally in Figure 5, there is shown an alternative structure, to show the flow of water injected again into the production zone is located below the injection zone 78 of the 76 expected. 潜入式马达沈、泵观和分离器34可以与参看图1描述的方式类似的方式连接,且方向改变装置38连接到分离器34的井上方向。 Shen submerged motor, pump and separator 34 concept can be connected in the manner described with reference to FIG. 1 in a similar manner, and the direction changing means 38 is connected to the separator 34 uphole direction. 方向改变装置38连接到管道80,所述管道80向井下延伸,以引导被改变方向的流体通过下封隔器82。 Direction changing means 38 is connected to the conduit 80, the conduit 80 extends downhole to change the direction of fluid being guided through the lower packer 82. 下封隔器82将生产区78与位于封隔器82下方的注水区76分离开。 Lower packer 82 78 production area located below the packer 82 is separated from the injection zone 76. 在该实施例中,水流行进通过管道80和尾管组件84。 In this embodiment, the water travels through a pipe 80 and tail pipe assembly 84. 尾管组件84延伸通过下封隔器82进入注水区76中,以便能够再次注入水组分。 Tailpipe assembly 84 extends through the lower packer 82 into the injection zone 76 to be able to inject water component again.

[0034] 图6示出了方向改变装置38的一个实施例的更详细的剖视图。 [0034] FIG. 6 shows direction of a more detailed cross sectional view of an embodiment of the device 38 to change. 类似地,图7示出了与定位在限流器容纳腔86中的限流器60组合的方向改变装置38的一个实施例的更详细的剖视图。 Similarly, Figure 7 shows the direction of the flow restrictor positioned in the receiving chamber 86 of the flow restrictor 60 combined for a more detailed cross-sectional view of an embodiment of the apparatus 38 changes. 限流器容纳腔86被构造成接收限流器60。 Flow restrictor receiving cavity 86 is configured to receive a flow restrictor 60. 在该特殊的示例中,水通道52基于离心式油/水分离径向上位于油通道50的外侧。 In this particular example, the water passage 52 based on the centrifugal oil / water separator is located radially outward of the oil passage 50. 油通道50从井下方向改变装置38延伸通过方向改变装置并向井上延伸经过方向改变装置,直到它与油管40、例如生产油管/连续油管连接。 Changing oil passage 50 extending from the downhole direction changing means to the apparatus 38 by extending through the uphole direction changing means, and tubing 40 until it is, for example, production tubing / coiled tubing connector. 水通道52从方向改变装置38下方延伸到方向改变装置38中。 Water passage 52 from the direction changing means 38 extends downward to the direction changing means 38. 水通道52会合到水通道88中,所述水通道88使水通道52与限流器容纳腔86连接。 Water passage 52 joined to the water passage 88, the water passage 52 and the passage 88 so that water flow restrictor receiving chamber 86 is connected. 在示出的实施例中,水通道88沿与水通道52大致垂直的方向延伸,从而,水流流经急转弯,例如90°转弯。 In the illustrated embodiment, the water passage 88 along a water channel 52 extending in a direction substantially perpendicular to, and thus, the water flows through sharp turns, e.g., 90 ° turns. 然而,转弯的角度可变化,且在一些应用中,它可以转弯较小,例如45°,或转弯更大,例如135°。 However, the turn angle may vary, and in some applications, it can turn a small, e.g., 45 °, or more turns, e.g., 135 °. 注入通道90连接在限流器容纳腔86与合适的通道、例如管道80之间,以便将井流体的水组分引导到期望的注水区76。 Water area of the injection channel 90 is connected to the flow restrictor chamber 86 with a suitable channel to accommodate, for example, between the pipe 80 in order to guide the water component of the well fluid to the desired 76.

[0035] 另外参看图8,示出了限流器60的一个实施例。 [0035] Also see FIG. 8, there is shown a flow restrictor 60 embodiment. 在该实施例中,限流器60包括本体92,所述本体中限定出上内腔室94和下内腔室96。 In this embodiment, the flow restrictor 60 includes a body 92, said body defining an inner chamber 94 and the lower inner chamber 96. 上内腔室94和下内腔室96由限流件、例如限流节流孔件62分隔,所述限流节流孔件具有流动通道/节流孔64,借此,流体流动被节流。 The inner chamber 94 and the lower inner chamber 96 from the limiting element, such as limiting the orifice 62 are separated, the limiting orifice member having a flow passage / orifice 64, whereby the fluid flow is Day stream. 节流孔件62和限流器本体92可以是同一部件或装配在一起的两个不同的部件。 Orifice member 62 and the flow restrictor body 92 may be two different members of the same parts or assemblies together. 整个限流器60和/或限流器节流孔件62可根据井流体分离应用场合是固定的或是可移除的。 The entire flow restrictor 60 and / or flow restrictor orifice 62 according to the well fluid separation applications is fixed or removable.

[0036] 在示出的实施例中,节流孔件62的节流孔64的直径比上内腔室94或下内腔室96 的直径小,但节流孔64的直径也可与上内腔室94或下内腔室96的直径基本上相同。 [0036] In the illustrated embodiment, the diameter of the orifice 62 of the orifice member 64 than the inner chamber 94 or lower chamber 96 of small diameter lumen, the diameter of the orifice 64 but also with the the inner chamber 94 or the inner chamber 96 under substantially the same diameter. 另外, 一个或多个通道98位于限流器的本体92中,且将上内腔室94与限流器60外部的区域液压连通。 In addition, one or more channels 98 located in the body of the flow restrictor 92, and the inner chamber 94 of the flow restrictor 60 hydraulic communication outside the area. 另一通道100位于限流器60的井下端上,且提供了能通过下内腔室96与节流孔件62的底部连通的流动路径。 Another channel 100 is located on the downhole end of the flow restrictor 60, and provided at the inner chamber 96 through the flow path and the bottom of the orifice 62 in communication.

[0037] 当限流器60定位在限流器容纳腔86内时,通道98可使流体从水通道88通过通道98进入上内腔室94中。 [0037] When the flow restrictor 60 is positioned in the flow restrictor accommodating chamber 86, channel 98 can flow from the water passage 88 through the passage 98 to enter the inner chamber 94. 流体然后流过节流孔件62的节流孔64并流入到下内腔室96 中。 Then fluid flow orifice flowing through the orifice 62 of 64 and into the inner chamber 96 under. 流体、例如水从下内腔室96流过通道100并流出限流器60,以用于再次注入到期望的区、例如注水区76中。 Fluid, such as water from the inner chamber 96 through the passageway 100 and out of the flow restrictor 60 to be used for injection again to the desired area, such as water injection zone 76. 多个密封件102、例如0形圈密封件可绕着本体92安装,以与限流器容纳腔96的内表面形成密封。 A plurality of seals 102, such as 0-ring seal 92 may be installed around the body to the inner surface of the flow restrictor receiving cavity 96 to form a seal. 在多种应用场合中,限流器60可以移除。 In many applications, the flow restrictor 60 may be removed. 附加性地替代性地,节流孔件62可被构造成是可更换的或可调节的,以便能够调节流动通道64的尺寸。 Additionally to the alternative, the orifice member 62 may be configured to be replaceable or adjustable to be able to adjust the size of the flow passage 64. 应当指出,限流器60可具有许多内部结构,所述内部结构能够使对流体的期望限流/节流便于分离井流体组分。 It should be noted that the flow restrictor 60 may have many internal structure, the internal structure enables the desired fluid flow restrictor / Throttle facilitate separation of the well fluid component.

[0038] 当可移除时,限流器60可包括连接件104,所述连接件104被设计成便于与工具66接合,以便放入限流器容纳腔86中和从限流器容纳腔86取出。 [0038] When the removable flow restrictor 60 may include a connector 104, the connector 104 is designed to facilitate engagement with the tool 66 so that the flow restrictor into the receiving chamber 86 and the flow restrictor receiving cavity 86 removed. 如较前所述,工具66可连接到多种传送装置68、例如电缆、钢丝或连续油管。 As compared before, the tool 66 can be connected to multiple delivery device 68, such as cable, wire or coiled tubing.

[0039] 在许多应用中,应用的分离技术和所选的限流器取决于与井流体相关的参数/特性,例如井流体容纳物。 [0039] In many applications, the application of separation technology and the selected flow restrictor depends on the well fluid related parameters / features, such as the well fluid containment material. 例如,井流体的容纳物可用于确定分离、生产和再次注入各种井流体组分的合适技术。 For example, the well fluid containment was used to determine the separation of production and injection wells suitable technique various fluid components again. 在一些应用中,传感器106可定位在井下,以确定所选的井流体的参数,例如井流体中的油/水/固体比例,如图9所示。 In some applications, the sensor 106 may be positioned in the underground, in order to determine the parameters of the selected well fluids, such as the well fluid oil / water / solids ratio, as shown in FIG. 来自传感器106的数据可以多种方式向井上传输,例如经过电线传输电信号,通过光纤传输光信号,经由无线传输技术传输无线电信号、声信号,以及其他合适的数据传输技术。 Data from the sensor 106 may be various ways to transmit uphole, e.g., via wires transmit electrical signals, optical signals transmitted through the optical fiber, via wireless transmission technology to transmit radio signals, acoustic signals, and other suitable data transmission technique. 替代性地,信号可传输到井下处理器108。 Alternatively, the signal can be transmitted to the downhole processor 108. 井下处理器108可用于向例如与可调节的节流孔件62连接的马达提供指令,以设定某一节流孔尺寸或执行其他井下功能。 Downhole motor processor 108 may be used for example to an adjustable orifice 62 connected to provide instruction to set a certain orifice size or perform other underground features. 根据应用场合,传感器106可位于分离器34的井流体进入口的下游、分离器34内、方向改变装置38内、限流器60内、分离器34外且井流体进入口30 的井下位置、分离器34外且井流体进入口30的井上位置、分离器34外且与井流体进入口30相同的高度处、井流体进入口30的下游、分离器的上游以及其他合适的位置。 Depending on the application, the sensor 106 may be located downstream of the separator well fluid inlet port 34, the separator 34, the direction changing means 38, the flow restrictor 60, separator 34 and the outer well fluid inlet port 30 of a downhole location, separator 34 outside the well fluid into the well location and port 30, 34 outside the separator and the well fluid inlet port 30 at the same height, the well fluid into the downstream port 30, upstream of the separator, and other suitable locations.

[0040] 再次参看图9,示出了限流器60的一个示例,所述限流器具有位于上内腔室94中的传感器106。 [0040] Referring again to FIG. 9, shows an example of a flow restrictor 60 having a flow restrictor located on the inner chamber 94 of the sensor 106. 在一个替代性的实施例中,传感器106可位于下内腔室96中;或多个传感器可位于上内腔室中、下内腔室中和/或其他期望位置处。 In an alternative embodiment, the sensor 106 may be located under the inner chamber 96; or more sensors may be located on the inner chamber, the inner chamber of the lower and / or other desired location. 根据期望采集的有关井流体的信息,传感器106可被设计成用于感测多种参数、例如温度、流率、压力、粘度、油/水比例或其他期望参数。 Depending on the desired fluid acquisition information about the well, the sensor 106 may be designed to sense a variety of parameters, such as temperature, flow rate, pressure, viscosity, oil / water ratio, or other desired parameters. 附加性地,一个传感器或多个传感器106可与遥测拾取装置110协作使用, 所述遥测拾取装置110集成在井系统20的方向改变装置38或另一合适的构件中。 Additionally, one or more sensors and telemetry sensors 106 may be used cooperatively pickup apparatus 110, the apparatus 110 integrated telemetry pickup direction changing means 20 well system 38 or another suitable member. 传感器106能够经由合适的遥测系统、例如电接触或“短传”遥测系统与井下处理器108或另一合适的数据收集系统通信。 108 or another suitable data sensor 106 can be via a suitable telemetry system, such as electrical contacts or "short pass" telemetry system and collection system of underground communications processor. 如前所述,从传感器106获得的信息也可用于调节节流孔64的尺寸。 As described above, the information obtained from the sensor 106 can also be used to adjust the size of the orifice 64. 例如,节流孔件62可包括调节机构111,所述调节机构可以机械、液压、电或其他方式调节。 For example, the orifice member 62 may include an adjustment mechanism 111, the adjustment mechanism may adjust the mechanical, hydraulic, electrical or other means. 在一个示例中,工具可在合适的传送装置68上下放,以便以机械方式致动调节机构111,从而改变节流孔64的尺寸。 In one example, the tool can be on a suitable transport means 68 delegated to mechanically actuated adjustment mechanism 111, thereby changing the size of the orifice 64.

[0041] 总体上参看图10,示出了分离器34和分离系统讨的另一实施例。 [0041] Referring to Figure 10 generally showing a separator and separation system 34 to discuss another embodiment. 在该实施例中, 分离器34被设计用于将井流体分离成另外的组分。 In this embodiment, the separator 34 is designed for separating the well fluids into additional components. 例如,分离器34可被设计成将井流体分离成油、水和固体,例如颗粒,以提供有益的分离和生产结果。 For example, separator 34 may be designed to be separated well fluids into oil, water and solids, such as particles, to provide a useful separation and production results. 井下流体分离技术的长期的成功应用中的一个因素是保持向注水区、例如区76的注入率。 The successful application of long-term downhole fluid separation technology is a factor in keeping the water area, such as district injection rate 76. 在生产操作中,注入率的降低可由在油和水分离之后被载送到注水区、例如区76的固体、例如颗粒引起。 In production operations, the injection rate can be reduced to the water contained in the region after the separation of oil and water, for example, a solid area 76, for example, causing the particles. 注水区的沙面上的固体的集聚可降低注入率。 Sand the surface of solids accumulation of water area can be reduced injection rates. 尽可能接近地将注入系数与实际一样长地保持为初始注入系数可有益于井下流体分离系统的连续操作。 Close to the actual injection coefficient maintained as long as the initial injection coefficient can be beneficial downhole fluid separation system of continuous operation possible. 生产可通过独自地限制在注水区处沉积的固体量或与注水区增产干预措施相结合而得到改善。 Production can be solely limited to the amount of solids deposited at the water district or water district stimulation interventions combining improved.

[0042] 图10中示出的分离器34的实施例被设计成用于提供另外的固体排放流。 [0042] FIG. 10 shows an embodiment of the separator 34 is designed to provide additional solids discharge stream. 该流可用于将固体引导离开注水区76。 The stream can be directed away from the water for the solid region 76. 在一些应用场合中,固体排放流可与井流体的已被生产出的油组分再次组合,以便留下基本上没有固体的注入水流。 In some applications, the solids discharge stream can again be combined with oil have been produced well fluid components, so as to leave virtually no injection water solids.

[0043] 如上面对分离器34的描述,油组分、水组分和固体组分的分离可通过转动动态分离器、例如旋流分离器或离心分离器,利用转动产生的力根据密度分离原理实现。 [0043] As described in the face 34 of the separator, the oil component separated water component and the solid component by rotating dynamic separators, such as cyclone separator or centrifugal separator, the force generated by the rotation of separation according to the density realization of the principle. 当井流体转动时,较重的相/组分被分离到外转动半径处。 When the well fluid to rotate heavier phase / components are separated to the outer rotor radius. 例如,较重的固体可被分离到径向外侧区域,而较轻的水被分离到中间区域,且更轻的油被分离到较接近转动中心的区域。 For example, the heavier solids can be separated into the radially outer region, while lighter water is separated into the middle region, and the oil is separated into the lighter areas closer to the center of rotation. 该径向中心处的油组分(可能具有一些残留的水和/或固体)作为生产流被排放。 Oil component (which may have some residual water and / or solid) at the center of the radial flow is discharged as a production.

[0044] 请再次参看图10所示的实施例,分离器34包括固体通道112,具有高的固体浓度的固体流通过所述固体通道排放。 [0044] Please Referring again to FIG. 10 embodiment, separator 34 comprises a solid passage 112, having a high solids concentration of solids flow through the solid discharge passage. 如图所示,固体通道/排放口112相对于水通道52和油通道50位于径向偏外的位置。 As shown, the solid channel / discharge port 112 located radially biased with respect to a location outside of the water channel 52 and the oil passage 50. 当流进入分流器48时,通道50、52和112充当分离器区域46的出口。 When the stream enters the splitter 48, channel 50, 52 and 112 act as a separator outlet region 46. 在该示例中,固体是最重的组分,旋流/离心分离将固体(具有作为载送流体的一些水)分离到分离器部分46的最外的半径处。 In this example, the solid is the heaviest component, cyclone / centrifuged and the solid (as a carrying fluid having some water) separator to a separator at the outermost radius of the portion 46. 如前所述,油最轻,且被分离到转动中心,以产生油流。 As mentioned earlier, oil lightest, and is isolated from the center of rotation, in order to produce the oil flow. 大部分水被分离到油组分与固体组分之间的中间位置处,且基本上没有固体。 Most of the water is separated into an intermediate position between the oil component and the solid component, and substantially no solids. 基本上没有固体的该水流可经由上述技术排放到期望的注水区,例如注水区76。 Substantially solid in water can be discharged via the water injection technology to the desired area, such as water injection zone 76. 在注水区76处再次注入水流避免阻塞注水区76的可能性,从而避免损坏注水区。 In the injection zone 76 to avoid blocking the water flow again injected possibility region 76, so as to avoid damage to the water district. 井流体的最外的组分是含有最高比例的固体的固体组分,且该固体组分可行进到再组合区域114,并与例如油管40中的作为生产流的油流再次组合。 Components of well fluids outermost solid component containing the highest proportion of solids, and the solid component can travel to the recombination region 114, and for example in the production tubing 40 as oil flow combined stream again.

[0045] 在操作中,井流体混合物通过泵送系统M的潜入式泵28或另一合适的泵被驱动到分离器;34的分离器腔室46、例如旋流/离心腔室中。 [0045] In operation, a mixture of well fluids through the pumping system M submersible pump 28 or another suitable pump is driven to the separator; separator chamber 34 of 46, for instance cyclone / centrifugal chamber. 井流体通过井流体入口116流入分离器34的分离器部分46中。 Well fluid inlet separator 116 flows into the separator 34 through the well fluid section 46. 在分离器部分46内,井流体的组分被分离成油、水和固体组分,所述油、水和固体组分分别主要包括油、水和固体。 In the splitter section 46, the components of the well fluid is separated into oil, water and solid components, the oil, water and solid components, respectively, include oil, water and solids. 主要为油、水和固体的流然后通过分流器48分成组分流,且相应的组分流通过相应的油通道50、水通道52和固体通道112行进。 Mainly oil, water and solids stream is then divided into groups by shunting the shunt 48, and the respective groups through the respective bypass oil passage 50, the water passage 52 and the passage 112 travels solid. 井流体组分可通过分流器48的相应的油流出口118、水流出口120和固体出口122被引导到下游的合适的流动路径。 Well fluid component by the shunt 48 of the corresponding oil outlet 118, outlet 120 and solids flow outlet 122 is directed to the appropriate flow path downstream. 水通道52相对于油通道50径向偏外设置,固体通道112 相对于水通道52径向偏外设置。 Water channel 52 with respect to the oil passage 50 radially outer partial set, solid channel 112 with respect to the water channel 52 radially outer partial set. 作为示例,油通道50、水通道52和固体通道112可以为同心管道的形式,所述同心管道将相应的井流体组分引导到下游的期望位置。 By way of example, the oil passage 50, the water passage 52 and passage 112 may be in the form of solid concentric pipes, the pipes corresponding concentric wells fluid component to a desired position downstream of the guide. 例如,组分流可被引导到合适的方向改变装置38和/或通过合适的限流器60。 For example, the group split may be directed to the appropriate direction changing means 38 and / or by a suitable flow restrictor 60.

[0046] 如上面对各种井系统实施例的描述,井流体组分的分离,例如油、水和固体组分的分离可通过操控作用于各种井流体组分流上的背压得到改善。 [0046] As the foregoing description of various embodiments of a well system, the well fluid component separation, e.g., separation of oil, water and solid components can be manipulated by a variety of well fluid acting on the back pressure of the shunt group is improved. 在许多应用场合中,期望的背压可通过提供设置在油/固体流和/或水流中的可移除的限流器、可移除的节流孔件和/ 或可调节的节流孔实现。 In many applications, it is desirable back pressure by providing the oil / solids flow and / or water flow restrictor removable orifice member may be removed and / or orifice adjustable settings implementation. 然而,对于井流体组分流的各种组合,背压可利用多种装置产生, 以实现期望的生产结果。 However, for well fluid shunt group various combinations, the back pressure can be used to produce a variety of means, to achieve the desired production results. 限流器例如可设置在油/固体流、油组分流、水组分流和/或固体组分流中。 For example, the flow restrictor may be provided in an oil / solid flow, the oil group diversion, water diversion group and / or a solid group Shunting.
