Abstract

A single use setting tool and associated method for actuating a tool in a wellbore may include an inner piston with an annular wall defining a piston cavity. A portion of the inner piston including the piston cavity may be positioned within a central bore of an outer sleeve, and the inner piston and the outer sleeve may be slidable relative to one another. A portion of the inner piston may extend beyond an end of the outer sleeve and have a shock absorbing wedge positioned thereon, and the end of the outer sleeve may have a cutout for receiving the shock absorbing wedge. A bi-directional gas-generating power charge may be positioned in the piston cavity and include a power charge having a booster positioned in an indentation adjacent each of a first end and a second end of the power charge.

First claim

What is claimed is:

1. A single use setting tool for actuating a tool in a wellbore, the single use setting tool comprising:
an inner piston having a piston proximal end, a piston distal end opposite the piston proximal end, and a piston annular wall, wherein the piston proximal end includes a seal adapter portion and the piston annular wall defines a piston cavity;
an outer sleeve having a sleeve proximal end, a sleeve distal end, and a sleeve central bore extending from the sleeve proximal end to the sleeve distal end, wherein a portion of the inner piston including the piston cavity is positioned within the sleeve central bore, a portion of the inner piston extends beyond the sleeve distal end, and the inner piston and the outer sleeve are configured for axially sliding relative to one another; and
a shock absorbing wedge positioned on the inner piston between the sleeve distal end and the piston distal end, wherein
the sleeve distal end includes a cutout dimensioned for receiving a portion of the shock absorbing wedge.

2. The single use setting tool of claim 1 , wherein the wedge includes a first end and a second end opposite the first end, an annular body portion defining a passage extending through the wedge from the first end to the second end, and a rib and a channel formed in the body portion, wherein the inner piston extends through the passage of the wedge.

3. The single use setting tool of claim 2 , wherein the wedge has a tapered profile.

4. The single use setting tool of claim 3 , wherein the cutout in the sleeve distal end is frustoconically shaped.

5. The single use setting tool of claim 1 , further comprising a sleeve adapter connected to the sleeve distal end, wherein the sleeve adapter includes a bore extending through the sleeve adapter and substantially coaxial with the sleeve central bore.

6. The single use setting tool of claim 1 , further comprising a bi-directional gas-generating power charge positioned within the piston cavity.

7. The single use setting tool of claim 6 , wherein the bi-directional gas-generating power charge includes a power charge having a first end and a second end opposite the first end, a first booster positioned in a first indentation in the power charge adjacent the first end, and a second booster positioned in a second indentation in the power charge adjacent the second end.

8. The single use setting tool of claim 7 , wherein the first booster is positioned within a booster receiver of a first booster holder and the second booster is positioned within a booster receiver of a second booster holder.

9. The single use setting tool of claim 7 , wherein the power charge is contained within a power charge container.

10. The single use setting tool of claim 7 , further comprising an initiator holder positioned at least in part within the piston cavity and configured for receiving and retaining an initiator, wherein the first booster holder is positioned between the initiator holder and the power charge.

11. The single use setting tool of claim 10 , wherein the initiator holder is configured for retaining the initiator at a position substantially coaxial with the seal adapter portion of the inner piston.

12. A method of actuating a wellbore tool with a single use setting tool, comprising:
providing a single use setting tool, wherein the single use setting tool includes
an inner piston having a piston proximal end, a piston distal end opposite the piston proximal end, and a piston annular wall, wherein the piston proximal end includes a seal adapter portion and the piston annular wall defines a piston cavity,
an outer sleeve having a sleeve proximal end, a sleeve distal end, and a sleeve central bore extending from the sleeve proximal end to the sleeve distal end, wherein a portion of the inner piston including the piston cavity is positioned within the sleeve central bore, a portion of the inner piston extends beyond the sleeve distal end, and the inner piston and the outer sleeve are configured for axially sliding relative to one another, and
a shock absorbing wedge positioned on the portion of the inner piston that extends beyond the sleeve distal end, wherein the sleeve distal end includes a cutout dimensioned for receiving a portion of the shock absorbing wedge;

inserting a bi-directional gas-generating power charge into the piston cavity, wherein the bi-directional gas-generating power charge includes a power charge having a first end and a second end opposite the first end, a first booster positioned in a first indentation in the power charge adjacent the first end, and a second booster positioned in a second indentation in the power charge adjacent the second end, wherein
the step of inserting the bi-directional gas-generating power charge into the piston cavity includes inserting either the bi-directional gas-generating power charge first end or the bi-directional gas-generating power charge second end nearest the piston proximal end;

inserting an initiator holder into the piston cavity, adjacent to the one of the first booster or the second booster of the bi-directional gas-generating power charge positioned nearest the piston proximal end;
inserting an initiator into the initiator holder;
connecting the single use setting tool to the wellbore tool;
deploying the single use setting tool and the wellbore tool into a wellbore; and,
initiating the initiator.

13. The method of claim 12 , further comprising initiating, by initiation of the initiator, one of either the bi-directional gas-generating power charge first end or the bi-directional gas-generating power charge second end nearest the piston proximal end, and the power charge.

14. The method of claim 12 , wherein the step of initiating the initiator includes providing an initiation signal from a feedthrough electrical connection to the initiator.

15. The method of claim 14 , further comprising confirming, after initiating the initiator, that electrical communication between the feedthrough electrical connection and the initiator has been terminated.

16. The method of claim 12 , further comprising receiving the shock absorbing wedge in the cutout of the sleeve distal end to brake an acceleration of the inner piston relative to the outer sleeve, after actuating the wellbore tool.

17. The method of claim 16 , wherein the single use setting tool further includes a sleeve adapter connected to the sleeve distal end, the method further comprising disconnecting the sleeve adapter from the sleeve distal end after receiving the shock absorbing wedge in the cutout of the sleeve distal end.

18. A single use setting tool, comprising:
an inner piston having a piston annular wall that defines a piston cavity;
an outer sleeve having a sleeve proximal end, a sleeve distal end, and a sleeve central bore extending from the sleeve proximal end to the sleeve distal end, wherein a portion of the inner piston including the piston cavity is positioned within the sleeve central bore;
a bi-directional gas-generating power charge positioned within the piston cavity, wherein the bi-directional gas-generating power charge includes a power charge having a first end and a second end opposite the first end, a first booster positioned in a first indentation in the power charge adjacent the first end, and a second booster positioned in a second indentation in the power charge adjacent the second end.

19. The single use setting tool of claim 18 , wherein the first booster is positioned within a booster receiver of a first booster holder and the second booste
