According to 35U.S.C. § 119 (e), this patent document requires to submit on September 15th, 2006, name is called the U.S. Provisional Application sequence number the 60/825th of " Compression and Blowout Resistant Cable with CuttingsRemoval and Fluid Pumping Capabilities for use in Drilling ", the preference of No. 729, this patent is combined in this by reference.

Technical field

The embodiment of describing relates to for carry the flexible pipe of fluid or air through oil field environment.The embodiment of the flexible pipe of hydrocarbon exploration and production application has been described especially.

Background technique

Many hydrocarbon exploration and other application relate to uses cable and flexible pipe.This cable and flexible pipe can be used for providing under water or hydrocarbon subterranean environment and ground location between be connected.The operating personnel of hydrocarbon applications equipment can be positioned at ground location.Can be by hydrocarbon instrument guiding and service below described hydrocarbon applications cable and flexible pipe Wei Gai position.The example of hose for hydrocarbons can comprise especially for carrying compressed-air actuated earthquake gun hose, for transmitting the drilling well flexible pipe of landwaste and drilling fluid and even for compressed fluid and instrument being delivered to the flexible tube of subsurface environment.

All hose for hydrocarbons as noted above generally include: such as the inner core of the polymer of nylon or teflon (PTFE), described inner core is surrounded by the stress element of strengthening braiding or circumvolution (served), that is to say, twist into the parts of cable or winding.Conventionally also will use sheath, thereby pack this hose part into and the outer surface of flexible pipe is provided.These enhancement stress parts can be such as Kevlar ^tMaramide-fibre or other applicable material, be configured to contribute to prevent flexible pipe explosion.That is,, for many hydrocarbon applications, pressure fluid or air can be driven through flexible pipe.Therefore, can use enhancement stress parts to help guaranteeing the to drive pressure by flexible pipe can not cause flexible pipe explosion, this can make it invalid.Explosion also can make to be connected to any hydrocarbon equipment or the fragile flexible pipe of the instrument environmental conditions around of flexible pipe.Therefore, effectively strengthening may be very crucial for the operation of hydrocarbon flexible pipe.

As indication, strengthen components normally surrounds the Kevlar of the core of flexible pipe ^tMfabric.Kevlar ^tMit is the material that weight is quite light and pliable and tough.It is also strong material, has the approximately 5 dual intensities-weight rate than the steel of identical weight.Therefore,, in the flexible while providing to a certain degree, when extra high pressure-driven is passed through the core of flexible pipe, it also is extremely applicable to helping to avoid the explosion of hose for hydrocarbons.Although strengthen components may be enough to avoid the explosion of flexible pipe, its flexible nature can not help avoid the compression of flexible pipe, for example, when being guided through High Pressure Difference environment.Therefore, the material that the sheath of hose for hydrocarbons is normally harder, can bear High Pressure Difference, avoids better collapsing and being out of shape simultaneously.

In the situation that hydrocarbon applications is flexible tube application, stainless steel outermost surface sheath can be used for guaranteeing that flexible tube flexible pipe can fully hold out against high down-hole pressure reduction and not occur significantly collapse or be out of shape.Yet along with this stainless steel sheath is by the turnover of spiral repeatedly well, it is easy to along with the time is tired flexible tube flexible pipe, thereby is subject to plastic deformation along with it constantly straightens with spiral.Along with the increase of amount of deformation, for example, with regard to its diameter, along with the increase of the overall dimensions of flexible pipe, this tired possibility of hose fracture that causes increases.Therefore, the external diameter of flexible tube flexible pipe may be limited to be generally and is less than approximately 1.5 inches.

Except worrying from using the fatigue of metal or other relatively not pliable and tough sheath, aramid and other porous material fiber are used for to also existent defect of reinforcement strengthen components.For example,, by the thousands of fibrous Kevlar yarns of the small circular element of utmost point porous in particular.Therefore, significantly the air of quantity is trapped in the layer of Kevlar strengthen components conventionally.Therefore,, when appearing at High Pressure Difference environment, any breakage of sheath material is easily subsided whole flexible pipe immediately.That is,, once sheath is crossed in the leakage of High Pressure Difference fluid or air, traditional porous aramid fibre reinforcing material cannot bear the compressive force applying on it.Thereby this hose for hydrocarbons subsides.

Unfortunately, do not have at present enough modes to eliminate the porosity of aramid fibre bundle, with when being subject to High Pressure Difference environment, provide the increase of flexible pipe or optional defence line.For example, Kevlar ^tMbe highly perfect material, generally include smooth and filament surface oiliness, make it be difficult to fill, or otherwise eliminate its porosity.Alternatively, metal armouring therein or wire material are as in the situation of strengthen components, and it is subject to making its frangible treatment conditions, and often to preventing that flexible pipe explosion has the validity reducing.That is, metal strengthening parts can be integrated in the core material of flexible pipe, to eliminate porosity.Yet the condition that metal bears to obtain this integration easily makes metal frangible and invalid.

Embodiment

With reference to specific hose for hydrocarbons, embodiment is described.The special construction of flexible tube, umbilical probing and earthquake gun hose is described.Yet, can use various structures.In any case the embodiment of description may comprise layer of material, it has and distributes by electromagnetism target wherein, to realize when the Electromagnetic Heating and the encirclement relation of strengthen components.This can adopt substantially the harmless mode of strengthen components is realized.

Referring now to Fig. 1, an embodiment of hose for hydrocarbons 100 is presented in the hydrocarbon well 190 being limited by the borehole wall 195.This flexible pipe 100 is configured to carrying through the multiple pressure of its centre gangway 180.For example, even, for the external diameter that surpasses approximately 1.5 inches, in one embodiment, according to the application in well 190 interior execution, flexible pipe 100 also can carry from atmosphere and be pressed onto up to approximately 20,000PSI or larger pressure.In addition, well 190 itself can provide and at below ground, extend the hyperbaric environment (referring to Fig. 4) of several thousand feet.Therefore,, according to specific environment, between centre gangway 180 and well 190, may there is high pressure reduction.Therefore, as described in detail below, hose for hydrocarbons 100 is configured to stand High Pressure Difference through passage 180 to avoid explosion, also stands from the High Pressure Difference of the external environment condition such as well 190, thereby avoids compressive strain simultaneously.That is, flexible pipe 100 is hose for hydrocarbons of compression resistant and explosion.

Continue to see figures.1.and.2, also with reference to Fig. 4, flexible pipe 100 can comprise traditional external jacket 175, and it is substantially by the remainder of flexible pipe 100 and external environment condition and relative pressure isolation.For example, in Fig. 1,2 and 4 embodiment, flexible pipe 100 can be used as flexible tube, and it is configured for transferring cleaning instrument 450 or through the miscellaneous equipment of well 190, in described well, it is level or high deflection structure.For this application, sheath 175 can be deformable carbon or Stainless Steel Tube or other traditional material.Alternatively, consider that this material is easy to tired by repeated deformation, sheath 175 can be deleted by integral body.In this embodiment, below the exposure inner tube 101 describing in detail can be applicable to determining size and be used as the flexible pipe 100 without any sheath.Owing to substantially lacking firm and integral body or the single features of porous inner tube 101, this of this flexible pipe 100 can arrangement be possible.

Just at sheath, using for example Kevlar 175 times ^tMtraditional flexible pipe of porous strengthen components in, such as that of Fig. 1 and Fig. 2, for example, at flexible pipe 100 around (in well 190) under the situation of High Pressure Difference, this sheath 175 helps avoid subsiding of flexible pipe 100.Yet in the embodiment of here describing, with respect to its multiple parts 150,200,201, directly the inner tube 101 of the flexible pipe 100 in sheath 175 is integral body or single structure substantially.That is,, no matter have multiple different parts 150,200,201, inner tube 101 lacks any air or substantially through open spaces wherein.Therefore, can occur the destruction due to fatigue external jacket 175 somewhere, flexible pipe 100 there will not be and anyly subsides significantly.

For example,, in particular with reference to Fig. 1, even break somewhere and inner tube 101 fails to isolate completely with well environment in the situation that, also can avoid the pressurized of the fluid of artesian well 190 to flow at sheath 175.Substantially the overall permanence of this inner tube 101 does not provide passage to this inflow of compression fluid.In fact, in the optional embodiment of mentioning in the above, compression resistant sheath 175 can be deleted by integral body, and inner tube 101 can be constructed to be applicable to size, thickness and rigidity, to bear the different pressure reduction that may occur during applying.

The inner tube 101 of Fig. 1 and 2 comprises adopts the multiple different parts 150,200,201 that concentrate in together in this way, so that above-mentioned basic overall permanence to be provided.A kind of in these parts can be arranged on material cores 275 base material layer 201 around.This material cores 275 can limit the centre gangway of flexible pipe 100, and base material layer 201 can be such material, and this material is compatible for the material that is attached to material cores 275.For example, in one embodiment, material cores 275 is given polymer, and base material layer 201 is mainly comprised of identical polymer.

This base material layer 201 can comprise that distribution is by electromagnetism target (electromagnetictarget) 250 wherein.Strengthen components 150 can adopt uniform mode to be longitudinally connected to around base material layer 201, cover its approximately 20% and approximately between 99%.As shown in Figure 2, when strengthen components 150 can adopt wire armouring form and structure, base material layer 201 still with the relation of strengthen components 150 in surrounding.Therefore, between strengthen components 150 and base material layer 201, substantially there is not air or space.Similarly, outer layer material 200 can be arranged on around strengthen components 150 equably, so that: it also can contact and be attached to base material layer 201, wherein allows as shown in Figure 2 the space between the wire armouring of strengthen components 150.Above-mentioned sheath 175 can be positioned at around inner tube 101, completes the structure of the flexible pipe 100 of Fig. 1.

The said structure of flexible pipe 100 has improved resistance to explosion and resistance against compression.That is, not only to rely on sheath 175 to provide resistance against compression, the structure of inner tube 101 own adopts the mode of wherein using traditional porous aramid or like fibrous material not to obtain that resistance against compression is provided.Therefore,, when being arranged in High Pressure Difference environment, the fatigue of sheath 175 unsuccessfully unlikely causes subsiding of flexible pipe 100 with isolating.Utilize identical mark (token), by using strengthen components 150, it is different from traditional aromatic copolyamide, and the encirclement structure of material layer 200,201 is provided itself, and flexible pipe 100 comprises resistance to burst.This strengthen components 150 can comprise winding or braided metal line.Selectively, can use interlocked metallic band.In one embodiment, strengthen components 150 is brass, and material layer 200,201 is mainly polymeric base layer, for fusing in its vicinity.As indirectly mentioned above, this polymer can be identical for the material of core 275 with selection.Therefore, as described in detail later, during manufacture, inner tube 101 combination continuously from inside to outside.

By strengthen components 150, imbed (in material layer 200,201) in the material of inner tube 101, the said structure of this flexible pipe 100 is obtained resistance to explosion and resistance against compression.Yet as also pointed out, this strengthen components 150 is suitably for alloy or the metal such as brass, it can worsen or to a certain degree frangible when being exposed to extreme induction heating temperature.And, from the position of manufacture and formability, may when extruding, be difficult to provide base material layer 201 strengthen components 150 around.Therefore, describe in detail below with strengthen components 150 and compare, in the mode of preferential heating and melting layer 200,201, convert material layer 200,201 to strengthen components 150 structure around so that inner tube 101 has the technology of the overall permanence of pointing out.

Referring now to Fig. 3, add with reference to Fig. 2, the flow chart of demonstration has been summed up an embodiment that forms hose for hydrocarbons as above.Namely, as 330 indications, form electromagnetism target 250 and mixture that can extruded material.This mixture will be used to form above-mentioned layer 200,201 (referring to 345,375) of the hose for hydrocarbons 100 of Fig. 1.As 315 and 345 indications, this mixture can be extruded on the material cores 275 of the pipeline of pointing out in the above at first.Adopt in this way, material cores 275 can provide solid basic unit, and succeeding layer 200,201 can be extruded around it.Alternatively, material cores 275 and base material layer 201 can be extruded jointly, or in one embodiment, inner tube 101 can not formed in the situation that having separative subsurface material core 275 completely.

Continuation is with reference to Fig. 2 and Fig. 3, and as 390 indications, electromagnetism target 250 and said mixture that can extruded material are configured to utilize the thermal conductivity of 250 pairs of Electromagnetic Heatings of target.For example, the material that target 250 is selected has the heat conduction responsivity larger to Electromagnetic Heating than the material of strengthen components 150.Therefore,, between the period of heating as shown in 390, layer 201 and/or 200 can be melted and be deformed into the encirclement relation with the form of strengthen components 150, makes parts 150 not accept to cause the heating of its any obvious friability or other deterioration.

In one embodiment, shown in mixture be carbon based fibers target, distribute by for example, such as the tradition of polyimide (nylon) or PTFE can extruded polymer.This target can account for approximately 15% of mixture, preferably approximately 2% with approximately between 8%.On the other hand, can select for strengthen components 150 compared with low heat conductivity material such as brass.Therefore, as the application of the Electromagnetic Heating of 390 indications, may be infrared heating, can cause fusing and the distortion of layer 200,201, and can significantly not damage strengthen components 150.In this embodiment, when being exposed to infrared heating, carbon fiber target 250 may be approximately 20 times of thermal conductivity of brass strengthen components 150.Therefore, for example,, in the situation that strengthen components 150 does not arrive harmful temperature (for brass over approximately 900 ℃), can obtain effective fusing and the distortion of polymeric layer 200,201 substantially.Except above-mentioned those polymer of mentioning, other polymer also can be for layer 200,201 and/or core 275.These can comprise fluoropolymer, polyolefin, high-strength thermoplastic plastics, thermoplastic elastomer (TPE), or even polyester or polyethers polymer.

As 360 indications, before as the Electromagnetic Heatings of 390 indications, strengthen components 150 is wrapped in around base material layer 201.Yet in one embodiment, strengthen components 150, during base material layer 201 winding around can appear at Electromagnetic Heating, may start Electromagnetic Heating before completing winding.In addition, the winding of strengthen components 150 can comprise strengthen components 150 wire braiding or interweave, to increase resistance to explosion or the compression resistance (referring to Fig. 1) of hose for hydrocarbons 100.

As mentioned in the above and 345 and 375, electromagnetism target 250 and mixture that can extruded material can be used for any one of base material layer 201 and outer layer material 200.From the viewpoint of manufacturing, many selections can be used for realizing layer 200,201 in strengthen components 150 fusing distortion around.For example, and then or in conjunction with providing strengthen components 150 as mentioned above, can carry out Electromagnetic Heating.In this occasion, as in 375 indications, outer layer material 200 can then be extruded on strengthen components, then as shown in 390, applies further Electromagnetic Heating.Yet in optional embodiment, before adopting Electromagnetic Heating, outer layer material 200 can be extruded on strengthen components 150 so that: Electromagnetic Heating 390 be used to melt simultaneously strengthen components 150 around two-layer 200,201.

In another embodiment, during Electromagnetic Heating 390, at base material layer 201 structure thickness around substantially distortion in the situation that, can abandon separated outer layer material 200 at strengthen components 150 completely.In this embodiment, strengthen components 150 can have fully little profile and wire gap, effectively to realize this structure of base material layer 201 around.

Be worth mentioning: once the inner tube 101 of this flexible pipe 100 as above describes ground in detail, form, just substantially realized resistance to explosion and the compression resistant ability of flexible pipe 100., but except sheath 175, many parts can provide in inner tube 101 therefore.For example, this inner tube 101 can be wound around by the additional layer of strengthen components now, so that other resistance to explosion ability to be provided.Even can in inner tube 101, use aromatic copolyamide, and can not have a significant effect to reducing resistance against compression tool.In addition, the increase layer of strengthen components or other material layer even also can be wrapped in around sheath 175.

In addition, electric conductor can be wrapped in (that is, being longitudinally arranged on around outer layer material 200) around inner tube 101, or provides with core 275 integral body, to provide electric current conveying capacity to flexible pipe 100.Alternatively, about this point, metal strengthening parts 150 can double as conductor, and can even be used as the function of radiating fin.This metallic conductor can be copper, nickel or the aluminium of insulation (insulated), number from approximately 1 to approximately 60 or more changeableization.Conductor insulation sleeve around can be at U. S. Patent the 6th, insulating material and the layered dielectric structure described for 600, No. 108, and this U. S. Patent is combined in this by reference.

Referring now to Fig. 4, shown that hose for hydrocarbons 100 adopts the form of flexible tube, for the prune job of oil 401.As shown, this flexible tube flexible pipe 100 advances and enters well 190 from flexible tube guide rail 410 through sparger 430.This well 190 adopts horizontal structure, thereby requires sizable power to be applied to flexible pipe 100, so that it advances to clear position 490.Yet this flexible pipe 100 has sufficient pliability and manoeuvring performance, cleaning tool 450 is sent to the landwaste 470 at 490 places, position, for cleaning.

In the embodiment showing, landwaste 470 may block the fracture surface in the production of hydrocarbons region 199 of well 190 operation processes.Therefore, pressure fluid can drive through flexible pipe 100, and arrives cleaning tool 450, for the cleaning of landwaste 470.This fluid can be approximately 2, and 500PSI and approximately 15, transmits between 000PSI, and preferably approximately 5,000PSI transmits, to realize sufficient cleaning.Yet due to the resistance to burst of the flexible pipe 100 of describing in detail above, any obvious pressure reduction causing through flexible pipe 100 can not cause explosion.That is, by other, with reference to Fig. 2, strengthen components 150 and around sheath 175 have enough intensity to avoid explosion.

Except resistance to burst, the flexible pipe 100 of Fig. 4 is resistance to subsiding.For example, referring again to Fig. 2, before cleaning, flexible pipe 100 can have through approximately 100PSI wherein and the hydrodynamic pressure between 2,500PSI, and compares with the interior pressure of well 190 itself, may be extremely low pressure reduction.Yet any obvious inflow that compatible integral body relative to each other of strengthen components 150 and peripheral layer 200,201 or unified characteristic can not make the hydrodynamic pressure of artesian well 190, to cross sheath 175, and enters along inner tube 101, thereby causes subsiding of flexible pipe 100.That is, even, in the situation that has worsened sheath 175 isolated location and make to pressurize well fluids contact inner tube 101, thereby also can avoid pressure to introduce under sheath 175, cause flexible pipe to subside.

In one embodiment, although the outer surface of flexible pipe 100 is whole, expose, replace enough inner tubes 101 thick and that firmly can not subside to bear the pressure reduction in the well 190 of mentioning, still can abandon sheath 175.This may relate to the slightly less flexible inner tube 101 of use.Yet owing to having removed more not pliable and tougher steel sheath 175, difference may be greater than and make up.That is,, owing to lacking sheath 175, may provide overall more pliable and tougher flexible pipe 100.In the situation that flexible line is applied, this can allow to use to have and improve effective flexible tube flexible pipe 100 that flexible external diameter surpasses 1.5 inches.

Referring now to Fig. 5, an optional embodiment of the hose for hydrocarbons 500 in using is described.In this embodiment, flexible pipe is the umbilical drilling well flexible pipe 500 using at well sites 501 places.Mud and landwaste 560 can be extracted from Production Regional 599 by drill bit 550, and through flexible pipe 500.Through flexible pipe 500 being attached to from the main drilling line 510 of boring tower 575 operations of top, this drilling mud and landwaste 560 can be sent to main shaft 590.This boring tower 575 can be connected to traditional recycle pump assembly 580, comprises slurry pump and storage tank.In this embodiment of Fig. 5, flexible pipe 500 is fully firm in from drill bit 550 slurry conveyed and landwaste 560, can not cause explosion to be subsided.

In another embodiment shown in Fig. 6, hose for hydrocarbons is used as the earthquake gun hose 600 at 601 places, underwater exploration position.In this embodiment, approximately 1, the air between 000PSI and about 3000PSI can penetrate through several flexible pipes 600 of the ship shape vessel 675 end towing by 601 places, position.The air penetrating can be used for producing seismic waves 625 from the rifle receiver assembly 650 in flexible pipe 600 end.For potential below production area 699, this seismic waves can turn back to assembly 650 by the relevant information of hydrocarbon.Although pressure reduction can increase through between the allotment period shown in flexible pipe 600 at air and reduce therein At All Other Times, due to the feature of describing in detail above, flexible pipe 600 comprises the ability of avoiding explosion and subsiding.

The application as flexible tube with reference to it of the above-mentioned detailed embodiment of this hose for hydrocarbons 100.Yet the hydrocarbon applications of other type can be benefited from the flexible pipe of while compression resistance and resistance to explosion.For example, as shown in Figure 5, hose for hydrocarbons 500 can adopt for delivery of landwaste, mud, drilling fluid and other rubble and use to the brill rope form of well 590.In addition, as shown in Figure 6, hose for hydrocarbons 600 can adopt for the form of the rifle cable of earthquake hydrocarbon exploration and use.

The embodiment of above-mentioned hose for hydrocarbons has realized resistance to burst, and mainly do not rely on aromatic poly-amide fabric, maybe may not make easy other material by compression of flexible pipe.As a result, the fatigue of hose sheath and fragmentation can not cause the compression of flexible pipe.This is the result of using the lower floor's inner tube that adds the strengthen components that is generally wire or element, and described stiffening element is evenly surrounded by the material layer of inner tube, causes atresia unification or whole inner tube structure substantially.Therefore, in conjunction with resistance to burst, can avoid pressure fluid to enter inner tube, and from contiguous flexible pipe, cross sheath and enter inner tube, cause it to subside.In fact, enough thick and firm so that aforementioned resistance against compression to be provided in the situation that in inner tube, be the pliability that increases flexible pipe, sheath can be eliminated thinner or completely.In addition, just provide with regard to the resistance to burst of flexible pipe, the non-porous and overall structure substantially of inner tube can adopt avoid making strengthen components accept to make that it is frangible, worsen or otherwise the mode of compromise treatment conditions realize.

Description above provides with reference to currently preferred embodiments.Field under these embodiments and the technician of technology are to be understood that: in the change of description scheme and operating method with change can be in the situation that do not deviate from principle and the scope of these embodiments and put into practice in implication.In addition, description above should not be read as describe and in the accompanying drawings shown in accurate structure, and should be understood and be there is it the most completely and the appended claim of the most suitable scope is consistent and be that claim is supported.
