Description
- In the resource recovery and fluid sequestration industries, actuation configurations that rely on hydrostatic pressure in some way are prevalent. Often such configurations include an atmospheric or other lower pressure chamber that is used relative to hydrostatic pressure in a downhole environment to cause a mechanical device to move. Interlocks are sometimes desired since it may be possible to experience early actuation of hydrostatic driven configurations. It is well known that early actuation in a downhole environment is costly and hence to be avoided. Interlocks have been used and generally function well but they take up wall thickness in many tools that employ them. If wall thickness is available without requiring the outside diameter to be large than the available space in the borehole or without requiring the inside diameter to be such that flow therethrough is restricted, then such interlocks are fine. Where one or both of these issues are presented however, commercially available interlock systems fail to support the industry need. The art will well receive solutions to this issue.
- An embodiment of a hydrostatic module interlock for a downhole tool including a piston having fingers extending from a body thereof, a piston mandrel telescopically arranged with the piston, and a retaining piston disposed to prevent finger deflection in the first position and allow finger deflection in the second position.

- Referring to
FIGS. 1-4 , a tool having ahydrostatic module interlock 10 is illustrated. The tool may be of any type (such as a packer) that uses hydrostatic pressure to move in some way and requires that control be maintained over actuation timing. Theinterlock 10 as disclosed herein provides highly reliable lockout of the hydrostatic module until threshold conditions are met. The art has found that with increasing demand for high pressure downhole systems for production, injection and sequestration, for example, issues regarding wall thickness for burst and collapse ratings are presented that conflict with desired bore diameter dimension. Theinterlock 10 solves the problem by supporting a larger bore diameter with standard size outside diameter while also producing an acceptable burst/collapse rating. - The
interlock 10 includes apiston 12 having a number offingers 14 extending from a body 16 of thepiston 12. Thefingers 14 are deflectable fingers such as collet fingers and may include gripping ends 18. Gripping ends 18 may be toothed structures, wickers, or may simply be of a slightly larger radial dimension such that the fingers, and hence thepiston 12 cannot move longitudinally along apiston mandrel 20, with which the gripping ends 18 are engaged if thefingers 14 cannot deflect. A retainingpiston 22 is slidably disposed upon thepiston mandrel 20 and engageable with thefingers 14 to prevent thefingers 14 deflecting until the retaining piston is moved from engagement withfingers 14. In an embodiment, the retainingpiston 22 cannot move along thepiston mandrel 20 until a threshold force is applied that will cause release of arelease configuration 24, which in some embodiments may be a release member or shear member. In the embodiment ofFIGS. 1-7 , the retainingpiston 22 includes aring 26 that engages with thefingers 14 in a first position. Thering 26 is illustrated engaging a radially outwardly positioned perimetrical surface of thefingers 14 to physically impede radially outward deflection of thefingers 14. It is also possible that thering 26 could be configured to be received in an annularly shaped recess in the ends offingers 14. This provides the same result that while in the first position, thefingers 14 cannot be deflected radially outwardly. Without radial deflection, the fingers cannot disengage from thepiston mandrel 20 for longitudinal movement relative thereto. The embodiment that places thering 26 radially outwardly of the perimetric surface of thefingers 14 is easily appreciated fromFIGS. 3 and 4 where the first and second positions of theinterlock 10 are illustrated sequentially. The cross-section views ofFIGS. 6 and 7 make evident the radially outwardly defected position of fingers 14 (FIG. 6 ) and the radially undeflected position of the fingers 14 (FIG. 7 ). In some variations of the embodiment ofFIGS. 1-7 , thepiston mandrel 20 may include agripping feature 28 to engage with the gripping ends 18 in the first position ofinterlock 10. As illustrated thefeature 28 may be wickers 30, for example, that engage the gripping ends 18. In use, theinterlock 10 begins in the first position, which is shown inFIG. 1 . Pressure inchambers port 38 tochamber 40 whereat theretaining piston 22 is hydraulically loaded against theatmospheric chamber 36. With the differential pressure experienced across retainingpiston 22, therelease configuration 24 is loaded to the threshold force and releases. Continued hydraulic pressure causes theretaining piston 22 to move rightwardly in the figure and out of contact with thefingers 14. This is illustrated inFIG. 2 althoughFIG. 2 is also after thepiston 12 is moved leftwardly in the Figure. Thepiston 12 is moved all the way to the left (second) position because the hydrostatic pressure throughport 38 creates a differential acrosspiston 12 relative toatmospheric chamber 34. The differential makes thepiston 12 want to move such that once the retaining capability of thefingers 14 being locked to thepiston mandrel 20 is released,piston 12 will indeed move leftwardly of the Figure. - In another embodiment, referring to
FIGS. 8-12 ,interlock 11 includes many working parts identical to (or nearly so)interlock 10 and these will not be directly addressed. Rather, the distinctions betweeninterlocks FIGS. 8-12 are helpful for understanding of the embodiment, it isFIG. 13 that provides the greatest elucidation of the distinction of this embodiment to the embodiment ofFIG. 1 . Thefingers 50 includeside walls 52 while theretaining piston 54 includesappendages 56 havingside walls 58. Each of the side walls is at an angle that is non radial relative to acenter axis 60 of theentire interlock 11. By viewingFIG. 13 , one can appreciate that with retainingpiston appendages 56 engaged withfingers 50, the fingers are not permitted to deflect radially outwardly. The angles of theside walls ring 26 from engagement with thefingers 14, theappendages 56 are removed from engagement with thefingers 50 instead. - Referring to

6. The interlock as claimed in claim 1 wherein the retaining piston includes a ring adjacent perimetrical surfaces of the fingers.
7. The interlock as claimed in claim 1 wherein the retaining piston includes retaining appendages engaged with the fingers when in the first position.
8. The interlock as claimed in claim 7 wherein the appendages are interspersed with the fingers.
9. The interlock as claimed in claim 7 wherein the appendages include non radial angled side surfaces that engage finger side surfaces thereby preventing radial deflection of the fingers while the retaining piston is in the first position.
10. The interlock as claimed in claim 1 , further comprising a release configuration preventing movement of the retaining piston from the first position to the second position.
11. The interlock as claimed in claim 10 , wherein the release configuration releases at a threshold force on the retaining piston.
12. The interlock as claimed in claim 11 , wherein the release configuration is a shear member.
13. A method for actuating an interlocked tool comprising:
loading a release configuration to a threshold force;
releasing the release configuration;
moving a retaining piston out of a first position wherein the retaining piston physically impedes deflection of a finger of a piston;
deflecting the finger out of engagement with a piston mandrel telescopically arranged relative to the piston; and
moving the piston relative to the piston mandrel.
14. The method as claimed in claim 13 wherein the moving of the retaining piston is moving a ring out of contact with a perimetrical surface of the finger.
15. The method as claimed in claim 13 wherein the moving of the retaining piston is moving a retaining appendage out of contact with a side surface of the finger.
16. A borehole system comprising:
a borehole in a subsurface formation;
a string disposed in the borehole; and
a hydrostatic module interlock as claimed in claim 1 disposed within or as a part of the string.
