    TOOL FOR USE IN UNDERGROUND PRODUCTION OF HYDROCARBONS AND CIRCULATION VALVE TOOL.
    BACKGROUND OF THE INVENTION / FIELD OF THE INVENTION [001] The present invention relates, in general, to circulation valves and sliding glove tools. In particular aspects, the invention refers to mechanisms of action for these tools.
    DESCRIPTION OF THE PREVIOUS TECHNIQUE [002] Well-hole tools have been designed to be operated using a ball or plug, which is grounded in a seat within the drain hole of the tool column. The ball or plug serves to increase the pressure and / or redirect the flow of fluid through the tool, to operate it. Tools of this type include circulation valves, which are used to selectively open and close the side fluid flow holes in an index tool, to allow the fluid flowing axially through the tool to be diverted to the surrounding flow hole. Circulation valves of this type are described in US patents 4,889,199, issued to Lee, US patent 5,499,687, issued to Lee, US patent 7,281,584, issued to McGarian et al., And US patent 7,416,029, issued for Telfer et al.
    SUMMARY OF THE INVENTION [003] An exemplary circulation valve is described, which includes a substantially cylindrical housing, with a central axial flow hole and a piston sleeve disposed within the flow hole. The tool includes an external housing, which defines an axial flow hole. External side drainage holes are arranged through the housing. The housing retains a
    2/14 piston, having internal lateral flow holes, and the movement of the piston sleeve, inside the housing, will place the internal flow holes in and out of alignment with the external flow holes.
    [004] A registration mechanism is used to control the axial position of the piston sleeve inside the housing. This registration mechanism allows the tool to undergo an alternating cycle between a first operating position, in which the external flow holes are closed for fluid flow, and a second operating position, in which the external lateral flow holes are opened. for fluid flow. In a described embodiment, the registration mechanism includes a registration sleeve, with a shoulder path inscribed on it. The shoulders are driven by the housing and are arranged within the shoulder path to move between the various positions within the path, as the piston sleeve is moved axially. The axial position of the piston sleeve is governed by the location of the bosses within the boss path.
    [005] The tool also has an actuation mechanism, which allows the tool to be switched between its first and second operating positions, through falling balls or plugs, which are grounded in a ball seat inside the piston sleeve . In a currently preferred embodiment, the ball seat is formed by one or more clamps, which are retained within grooves in the piston sleeve. The actuation mechanism contains an expansion chamber, which holds the clamps in a radially restricted manner. The expansion chamber has chamber parts having different diameters. In one described embodiment, the expansion chamber has at least three camera parts having diameters
    3/14 progressively increasing.
    [006] Variable fluid pressure is used to move the piston sleeve axially downward against a thrust force, such as a spring. The downward movement of the piston sleeve moves the clamps into a part of the larger diameter expansion chamber. The larger diameter allows the clamps to move radially outward, releasing an actuation sphere. The tool requires that one actuation ball size moves the tool from a first operating position to a second operating position, and that a second actuation size moves the tool from the second operating position back to the first operating position.
    [007] During the process of spheres falling through the tool hole, an indication of positive feedback is provided to an operator on the surface by means of the resulting fluid pressure in the tool column, with which the operation of the tool is confirmed.
    [008] According to another aspect of the invention, the tool preferably incorporates a damper to control the relative movement speed of the piston and body, during operating cycles. The damper helps prevent damage to the operation of the tool registration mechanism.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0019] Figures 1 to 4 illustrate an exemplary circulation valve tool 10, which is constructed in accordance with the present
    5/14 invention. The upper part of the tool 10 is shown on the left side of Figures 1 to 4, while the lower part of the tool 10 is shown on the right side of Figures 1 to 4. The circulation valve tool 10 includes a generally cylindrical outer housing 12 , which has an upper axial end 14 and a lower axial end 16. The upper end 14 includes a threaded connection of the box type 18, and the lower end 16 provides a threaded connection of the pin type 20. The connections 18 and 20 are of a type known in the art to incorporate tool 10 into a tool column (not shown) and arranged in a well hole. The housing 12 defines a central flow hole 22 along its length. In a preferred embodiment, housing 12 consists of an upper index 24 and a lower index 26, which are threaded together at connection 28. External side fluid holes 30 are arranged by the housing 12.
    [0020] Located within the housing 12, and preferably within the lower end of the upper index 23, there is a staggered expansion chamber, shown generically at 32. Figure 1A illustrates that chamber 32 in more detail. As best shown in this specification, the expansion chamber 32 includes three camera parts 32a, 32b and 32c, having internal diameters that increase sequentially. Chamber part 32a has the smallest diameter. The part of the large diameter chamber 32c has the largest diameter. The intermediate diameter chamber part 32b has a diameter that is larger than the small chamber part 32a, but is smaller than that of the large diameter chamber part 32c.
    [0021] A registration chamber 34 is defined inside the housing 12, below the expansion chamber 32. One or more registration shoulders 36 are arranged by the housing and project towards the registration chamber
    6/14 register 34. Although only a single boss 36 is visible in Figures 1 to 4, it is currently preferred that there are multiple bosses 36, which are spaced angularly around the circumference of the housing 12.
    [0022] Below the recording chamber 34, a damping chamber 38 is defined inside the housing 12. Side filling holes 40 are arranged by the housing 12 and closed with plugs 42.
    [0023] A piston sleeve 44 is disposed within the drain hole 22. The piston sleeve 44 has a generally cylindrical body 46, which defines a central flow path 47. A flange 48 protrudes radially out of the body 46, and has orifices for internal radial fluids 50 arranged within it. The annular fluid seals 51 surround the body 46 and seal the surrounding housing 12, thereby isolating the fluid holes 50. Several longitudinal grooves 52 (see Figure 1A) are formed within the upper end of the body 46. Preferably , there are four such slots 52, three of which are visible in Figure 1A. However, there may be a different number of said slots 52, if desired. Also, preferably, the grooves 52 are spaced equidistantly around the circumference of the body 46. Each groove 52 contains a clamp 54, which can be moved radially in and out through the groove 52. It is currently preferred that the clamps 54 are generally rectangular in shape and have lower parts projecting inwards. The clamps 54 collectively form a ball seat, usually indicated by reference number 55. When the clamps 54 are located within the restricted diameter part 32a, the ball seat 55 will have a smaller diameter opening, so that both a smaller actuation sphere 84 and a larger actuation sphere
    7/14 can be seated on ball seat 55. When clamps 54 are located within the intermediate diameter chamber part 32b, ball seat 55 will provide a larger diameter central opening, so that the larger actuation ball 86 will still be captured by ball seat 55. However, smaller actuation ball 84 will pass through ball seat 55. However, smaller actuation ball 84 will pass through ball seat 55. When clamps 54 are located within the part of the larger diameter chamber 32c, the ball seat 55 will provide a central opening of an even larger diameter, which will allow both the smaller ball 84 and the larger ball 86 to pass through the ball seat 55.
    [0024] A registration sleeve 56 surrounds a lower part of the body 46 inside the registration chamber 34, and is movable within the registration chamber 34. Registration sleeve 56 is generally cylindrical, and has a radially enlarged portion 58. An annular spring chamber 60 is defined radially between the skirt 58 and the body 46 of the piston sleeve 44. The upper end of the registration sleeve 56 has an inwardly extending flange 62, which engages the body 46. A spring compression 64 surrounds piston sleeve 44, and generally resides within spring chamber 60. The upper end of compression spring 64 comes into contact with flange 62, while the lower end of spring 64 comes into contact with a buffer element annular 66, which is disposed within the recording chamber 34 and seals the recording chamber 34 of the damping chamber 38. It should be noted that a seal for annular fluid 67 forms a seal between the lower index 26 and the piston sleeve 44 The seals for flu 69 are located around and within the buffer element 66, to provide sealing against the piston sleeve 44 and the recording chamber 34.
    [0025] As can be seen with reference to Figures 5 to 8, the glove
    Record 8/14 56 has an outer radial surface 68, which has a shoulder path 70 engraved on it. The shoulder path 70 is shaped and sized to retain the inner ends of all shoulders 36 within it. The boss path 70 generally includes a central circumferential path 72. Several legs extend axially from the central path 72. The path 70 is designed so that the number of leg types is equal to the number of bosses 36, which are used with the path 70. Long legs 74 and short legs 76 extend axially down central path 72. In addition, long legs 78 and short legs 80 extend axially upward from central path 72.
    [0026] With reference again to Figures 1 to 4, it should be noted that a damping piston 82 is disposed within the damping chamber 38. Damping piston 82 is fixed firmly on piston sleeve 44, and contains a or more restricted fluid flow holes 83, which extend entirely through the damping piston 82. The fluid seal 85 radially surrounds the damping piston 82 and forms a fluid seal on the inner wall of the damping chamber 38. A hydraulic fluid fills the damping chamber 38, both above and below the damping piston 82.
    [0027] Tool 10 can be switched repeatedly between a first operating position, in which the external fluid holes 30 are closed for fluid flow, and a second operating position, in which the external fluid holes 30 are opened for fluid flow. fluid. For this to be done, the actuation balls 84 and 86 are dropped through the drainage hole 22 of the tool 10, to cause the tool 10 to be actuated between these positions. Ball 84 is smaller in size than ball
    9/14
    86. It should also be noted that, although spherical spheres are illustrated for both spheres 84 and 86, a spherical element is not necessary. In fact, data or buffers of other shapes and configurations can also be used and these are intended to be included within the general meaning of the word sphere, as used in this specification. When tool 10 is initially formed in a column of tools and extended into a drain hole, it is typically in the first operating position shown in Figure 1, although ball 84 is not present. The clamps 54, which form the ball seat 55, are located within the small diameter chamber part 32a of the expansion chamber 32. The clamps 36 are located inside the long extending legs 74 (see Figure 5) . In that position, the fluid flow through the lateral fluid holes 30 is closed by the registration sleeve 56. The internal fluid flow holes 50 are also not aligned with the external fluid flow holes 30, and the fluid seals 51 prevent the communication of fluid with the internal holes 50. The fluid can be drained, and the tools can be passed axially through the drain hole 22 of the tool 10.
    [0028] When it is desired to open the lateral fluid holes 30, to allow fluid communication between the flow hole 22 and the well hole, the smaller sphere 84 is dropped into the flow hole 22, in which it is seated in the seat of ball 55 provided by clips 54 (see Figures 1 and 1A). The fluid pressure is then increased inside the drainage hole 22, above the grounded sphere 84. The increased fluid pressure causes piston sleeve 44 and the fixed registration sleeve 56 to move axially downwardly with respect to housing 12 , as illustrated in Figure 2. The com-
    10/14 pressure 64 is compressed. The shoulders 36 will move along the path 70 to be located inside the legs extending upwards 36 from the path 70 (see Figure 6). As this axial movement occurs, the registration sleeve 56 and the piston sleeve 44 are rotated inside the housing 12.
    [0029] As the piston sleeve 44 moves axially downwards, to the first intermediate position illustrated in Figures 2 and 6, the clips 54 are moved to the part of the larger diameter chamber 32b of the expansion chamber 32. The larger diameter of the chamber part 32b allows the clips 54 to be moved radially outward and to release the small sphere 84, as shown. The projections 36 will be supported on the legs extending upwards, short 80 of the projection path 70, when the clips 54 are in position to release the ball 84. The released ball 84 can be captured by a ball catcher (not shown ) of a type known in the art, which is located inside the tool column below tool 10.
    [0030] After ball 84 has been released from ball seat 55, spring 64 will propel piston sleeve 4 and register sleeve 56 axially upwardly into housing 12. Upward movement of piston sleeve 44 and the registration glove 56 will end when the shoulders 36 are supported on the legs extending downwards, short 76 of the shoulder path 70. Tool 10 will then be in the second operating position illustrated in Figures 3 and 7. In this operating position, the internal fluid flow holes 50 of piston sleeve 44 are aligned with the external fluid flow holes 30 of housing 12, so that fluid can flow between the internal flow hole 22 and the surrounding well hole. It should also be noted that clips 54 are shown more
    11/14 once located radially within the chamber part 32a of the expansion chamber 32.
    [0031] When it is desired to return tool 10 to the first operating position (closed), illustrated in Figures 1 and 5, the largest ball 86 is thrown into the drain hole 22 and grounded at the ball seat 55. The fluid pressure is then varied and increased within the drainage hole 22 above the ball 86. The increased fluid pressure will drive piston sleeve 44 and registration sleeve 56 axially down into housing 12 and compress spring 64. Tool 10 is then in the second intermediate position illustrated in Figure 4. The shoulders 36 are moved to the long legs extending upwards 78 from the shoulder 70 (see Figure 8). Therefore, the clamps 54 are moved downwardly, towards the part of the enlarged diameter chamber 32c of the expansion chamber 32, thereby allowing the clamps 54 to be moved radially outwards properly, to allow the largest sphere 86 be released from ball seat 55.
    [0032] As the largest ball 86 is released from ball seat 55, spring 64 will propel piston sleeve 44 and register sleeve 56 axially upward again and return the tool to the first operating position illustrated in Figures 1 and 5. From that first operational position, it can once again be moved to the second operational position (Figures 3 and 7) and back by repeating the steps described above. It should be noted that tool 10 can be alternated between the first and second operating positions repeatedly by sequentially using a smaller sphere 84, followed by a larger sphere 86. Those skilled in the art will understand that, by virtue of the rebound path 70 surround registration sleeve 56 in a continuous manner, the steps described above can be repeated
    12/14 to make tool 10 cycle between operating positions.
    [0033] Only a smaller ball 84 will be useful for moving tool 10 from the first operating position (closed) to a second operating position (open). If a large ball 86 is grounded at ball seat 55, when tool 10 is in the first operating position (Figures 1 and 5), large ball 86 will not be released from ball seat 55, when seat 55 is moved to down towards the part of the chamber of intermediate diameter 32b (Figure 2). The shoulders 36 will be supported on the legs 80 of the shoulder 70 (Figure 6). The pressure inside the drain hole 22 will have to be varied, so that it is reduced, to allow the tool 10 to move to the position shown in Figures 3 and 7. Then, the fluid pressure can be varied again and increased inside the drainage hole 22, which will move the tool 10 to the second intermediate position shown in Figures 4 and 8, and the larger ball 86 will be released as the ball seat 55 is moved towards the part of the large diameter chamber 32c.
    [0034] In contrast, only a larger sphere 86 will be useful for moving tool 10 from the second operating position (open) to the first operating position (closed). If a smaller ball 84 is thrown with the intention of being grounded on ball seat 55, when tool 10 is in the second operating position (Figures 3 and 7), it will pass through ball seat 55 once again where the seat of ball 55 is located inside the chamber part of intermediate diameter 32b. Therefore, with the smaller sphere 84, the tool 10 is unable to be moved to the second intermediate position (Figures 4 and 8), because it will release the smaller sphere 84
    13/14 before the tool can reach the second intermediate position. [0035] During the movements of piston sleeve 44 and registration sleeve 56 described above, a damping assembly, which includes damping chamber 38 and damping piston 82, controls the relative speed of these components within the housing
    12. For example, as piston sleeve 44 is moved axially downwardly into housing 12 (as it would be when moving from the position shown in Figure 1 to the position shown in Figure 2), the damping piston fixed 82 will be propelled downward into the cushion chamber 38. The fluid below the cushion piston 82, within the cushion chamber 38, must be transferred by the cushion piston 82 through orifice 83, to accommodate the cushion piston 82. This transfer of fluid requires some time for it to occur, because orifice 83 is restrictive. Therefore, the rate of movement of the damping piston 82 and the fixed piston sleeve 44 is decreased.
    [0036] It should be understood that tool 10 provides an actuation mechanism, which has a ball seat 55, which will release balls of different sizes 84 and 86, when tool 10 is moved from both operating positions. It should also be noted that tool 10 is operated using actuation balls 84 and 86, which are of different sizes. Only the large ball 86 can close the tool 10, and the small ball 84 can open the tool 10. Therefore, it is easy for an operator to keep track of what position the tool 10 is in. This aspect helps to ensure that the inadvertent return of tool 10, for its first operating position, does not occur. This is because a smaller ball 84 will be released by ball seat 55, before it is moved by the registration sleeve 56 to the first operating position.
    14/14 nal, and only the use of a larger sphere 86 will work to return tool 10 to its first operating position.
    [0037] The description presented above is directed to the particular embodiments of the present invention, for the purpose of illustration and explanation. It will be evident, however, for those skilled in the art that many modifications and variations in the embodiment presented above are possible, without departing from the scope and spirit of the invention.
