Abstract
A downhole service tool is provided that may include a body having an interior passageway, at least one exit port through which fluid may flow from the interior passageway to an exterior of the tool, and at least one diverting channel adapted to cause fluid exiting the exit port to flow in a predetermined pattern, such as a helical or rotational flow path. The diverting channel may be in the form of a trough, and may also have a tapering width from its upper end to its lower end, where it meets the exterior of the tool. The diverting channel may also have a helical or other predetermined shape so as to facilitate the inducement of the desired flow pattern. By designing the tool so as to create a desired flow pattern, erosion of the tool by the exiting fluid flow is lessened. Related methods are also provided.

2. Description Of The Related Art.
[0003] It is known within the oil and gas industry to inject a variety of fluids or slurries into a downhole well through the use of a service tool connected to a service string. An example of such a service tool can be found in U. S. Patent No. 5,029,644 issued on July 9, 1991 to Szarka et al. Prior service tools are deficient, however, in that they are prone to being eroded by the exiting fluid, which erosion thereby shortens the life of the service tool. As will become apparent from the following description and discussion, however, the present invention overcomes the deficiencies of the previous devices and constitutes an improved and more efficient service tool for use in injecting fluids and slurries into a downhole well.

[000141 While the invention will be described in connection with the preferred embodiments, it will be understood that it is not intended to limit the invention to those embodiments. On the contrary, it is intended to cover all alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTION OF THE INVENTION
[000151 Referring to the drawings in detail, wherein like numerals denote identical elements throughout the several views, there is shown in Figure 1 a service string 10 positioned in a well 12.
-5a-The service string 10 may comprise coiled tubing, jointed tubing, or some other conduit. A service tool 14 constructed in accordance with the present invention is connected to the service string 10.
The service tool 14 may include a body member 22 having an exit port 16 and a diverting channel 18 that has a tapered region. The exit port 16 provides flow communication from an interior passageway of the service tool 14 to an exterior of the service tool 14. The exit port 16 and diverting channel 18 are shaped to induce a controlled, predefined flow pattern as fluid or slurry exits the tool 14.
[00016] Ina specific embodiment, the exit port 16 and diverting channel 18 maybe shaped to induce a circular or rotational flow into a well annulus 20 formed between the well 12 and the service string 10. To accomplish the controlled, predefined flow pattern, the exit port 16 and diverting channel 18 define a flow path that diverts the exiting fluid or slurry along a predetermined path. In a specific embodiment, the tapered region of the diverting channel 18 redirects the flow from the service tool 14 to produce the controlled, predefined flow pattern.
In a specific embodiment, as shown for example in Figure 2, the diverting channel 18 may follow a helical tapering path that produces a swirling fluid flow exiting the tool 14. It has been found that such a design extends the life length of the tool 14 significantly by reducing tool erosion by the fluid.
[000171 In use, as shown in Figure 1, the service tool 14 maybe positioned within the well 12 adjacent perforations 30. In addition, packers 28 (such as cup packers or other suitable isolation devices) may be provided above and below the service tool 14 so as to seal the annulus above and below the perforations 30 and thereby direct the treatment fluid exiting the tool 14 into a specific area of the formation, such as into the perforations 30.
[00018] Another specific embodiment of the present invention is shown in Figures 3-5. In this embodiment, it can be seen that the interior passageway 24 of the service tool 14 may be provided with threads 26 for connection to the service string 10. As is known to those of skill in the art, the interior passageway 24 of the service tool 14 communicates with a similar interior passageway in the service string 10. In this embodiment, as best seen in Figures 3 and 4, it can be seen that the tool 14 includes two exit ports 16 and two diverting channels 18. Each diverting channel 18 extends downwardly from a longitudinal axis of the tool 14 to the exterior of the tool 14.
Ina specific embodiment, the diverting channel 18 may be in the form of a trough, and may also be helically shaped. The width of the diverting channel 18 may gradually decrease in size from a first width at the longitudinal axis, or at an upper end of the diverting channel, to a relatively smaller second width at the exterior of the tool 14. Figures 3-5 further illustrate how fluid or slurry flowing down through the service string 10 will flow into the interior passageway of the service string 10 and then along the diverting channels 18 and out through the one or more exit ports 16 in a predefined flow pattern (e.g., swirling) as it exits the tool 14. When two or more exit ports 16 and diverting channels 18 are used, they may each work in unison with the others to further enhance the desired flow pattern.
[00019] Fluids or slurries maybe flowed from the surface through the service string 10 into the wellbore 12 and spotted or placed at the desired location in the well 12 through the exit ports 16 of the service tool 14. For example, stimulation or fracturing fluid may be injected into the well 12 via a service string 12 to inject fracturing fluid into perforated gas zones.
By use of the present invention in these and other fluid injection scenarios, the fluids or slurries will exit the service tool 14 in a desired flow pattern, thereby extending the life of the service tool 14 in relation to prior service tools.
[000201 Although only a few exemplary embodiments of this invention have been described in detail above, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the following claims. In the claims, means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not .only structural equivalents, but also equivalent structures. Thus, although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures.:

Each diverting channel 18 extends downwardly from a longitudinal axis of the tool 14 to the exterior of the tool 14.
Ina specific embodiment, the diverting channel 18 may be in the form of a trough, and may also be helically shaped. The width of the diverting channel 18 may gradually decrease in size from a first width at the longitudinal axis, or at an upper end of the diverting channel, to a relatively smaller second width at the exterior of the tool 14. Figures 3-5 further illustrate how fluid or slurry flowing down through the service string 10 will flow into the interior passageway of the service string 10 and then along the diverting channels 18 and out through the one or more exit ports 16 in a predefined flow pattern (e.g., swirling) as it exits the tool 14. When two or more exit ports 16 and diverting channels 18 are used, they may each work in unison with the others to further enhance the desired flow pattern.
[00019] Fluids or slurries maybe flowed from the surface through the service string 10 into the wellbore 12 and spotted or placed at the desired location in the well 12 through the exit ports 16 of the service tool 14.
