Abstract

Provided, in one aspect, is a downhole torque limiter, comprising a tubular housing; a pipe positioned within the tubular housing; one or more clutch mechanisms positioned between the pipe and the tubular housing, the one or more clutch mechanisms configured to move between a engaged state to fix the tubular housing relative to the pipe and a disengaged state to allow with the tubular housing to rotate relative to the pipe; and a fluid control system coupled with an exterior of the one or more clutch mechanisms, the fluid control system configured to allow the one or more clutch mechanisms to move from the engaged state to the disengaged state based upon sensing movement of the pipe relative to the tubular housing.

First claim

What is claimed is:

1. A downhole torque limiter, comprising:
a tubular housing;
a pipe positioned within the tubular housing;
one or more clutch mechanisms positioned between the pipe and the tubular housing, the one or more clutch mechanisms configured to move between an engaged state to fix the tubular housing relative to the pipe and a disengaged state to allow with the tubular housing to rotate relative to the pipe; and
a fluid control system coupled with an exterior of the one or more clutch mechanisms, the fluid control system configured to allow the one or more clutch mechanisms to move from the engaged state to the disengaged state based upon sensing movement of the pipe relative to the tubular housing, wherein the fluid control system includes a hydraulic pump configured to control fluid pressure against the exterior of the one or more clutch mechanisms.

2. The downhole torque limiter according to claim 1 , wherein each of the one or more clutch mechanisms includes a piston assembly.

3. The downhole torque limiter according to claim 2 , wherein the piston assembly is held in the engaged state by fluid pressure against the exterior of the piston assembly.

4. The downhole torque limiter according to claim 3 , wherein the piston assembly includes a spring, wherein the piston assembly is held in the engaged state by the spring.

5. The downhole torque limiter according to claim 1 , wherein the hydraulic pump reduces the fluid pressure against the exterior of the one or more clutch mechanisms to allow the one or more clutch mechanisms to move at least partially from the engaged state to the disengaged state.

6. The downhole torque limiter according to claim 1 , wherein the hydraulic pump suctions the fluid from the exterior of the one or more clutch mechanisms to move the one or more clutch mechanisms to a substantially disengaged state.

7. The downhole torque limiter according to claim 1 , further including a pressure relief valve configured to allow fluid from the exterior of the one or more clutch mechanisms to move to an interior of the of the one or more clutch mechanisms upon failure of the fluid control system and sensing a high-pressure situation.

8. The downhole torque limiter according to claim 7 , further including a one-way check valve configured to allow fluid to move from the interior of the one or more clutch mechanisms to the exterior of one or more clutch mechanisms when the high-pressure situation has been relieved.

9. The downhole torque limiter according to claim 1 , wherein the fluid control system includes electronics configured to sense movement of the pipe relative to the tubular housing and send a signal to a hydraulic pump of the fluid control system to allow the one or more clutch mechanisms to move from the engaged state to the disengaged state.

10. The downhole torque limiter according to claim 9 , wherein the electronics includes an acoustic sensor configured to sense the movement of the pipe.

11. The downhole torque limiter according to claim 1 , wherein the tubular housing includes an upper driver end and a lower driven end, wherein the upper driver end is fixed with respect to the pipe and the lower driven end engages and disengages with the pipe.

12. A well system, comprising:
a wellbore;
a tubing string positioned within the wellbore;
a torque limiter coupled with the tubing string, the torque limiter including:
a tubular housing;
a pipe positioned within the tubular housing;
one or more clutch mechanisms positioned between the pipe and the tubular housing, the one or more clutch mechanisms configured to move between an engaged state to fix the tubular housing relative to the pipe and a disengaged state to allow with the tubular housing to rotate relative to the pipe; and
a fluid control system coupled with an exterior of the one or more clutch mechanisms, the fluid control system configured to allow the one or more clutch mechanisms to move from the engaged state to the disengaged state based upon sensing movement of the pipe relative to the tubular housing, wherein the fluid control system includes a hydraulic pump configured to control fluid pressure against the exterior of the one or more clutch mechanisms.

13. The well system according to claim 12 , wherein each of the one or more clutch mechanisms includes a piston assembly, wherein the piston assembly is held in the engaged state by fluid pressure against the exterior of the piston assembly.

14. The well system according to claim 12 , wherein the hydraulic pump reduces the fluid pressure against the exterior of the one or more clutch mechanisms to allow the one or more clutch mechanisms to move at least partially from the engaged state to the disengaged state.

15. The well system according to claim 12 , wherein the hydraulic pump suctions the fluid from the exterior of the one or more clutch mechanisms to move the one or more clutch mechanisms to a substantially disengaged state.

16. The well system according to claim 12 , further including:
a pressure relief valve configured to allow fluid from the exterior of the one or more clutch mechanisms to move to a disengaged interior of the of the one or more clutch mechanisms upon failure of the fluid control system and sensing a high-pressure situation; and
a one-way check valve configured to allow fluid to move from the disengaged interior of the one or more clutch mechanisms to the exterior of one or more clutch mechanisms when the high-pressure situation has been relieved.

17. The well system according to claim 12 , wherein the fluid control system includes electronics configured to sense movement of the pipe relative to the tubular housing and send a signal to a hydraulic pump of the fluid control system to allow the one or more clutch mechanisms to move from the engaged state to the disengaged state.

18. The well system according to claim 12 , wherein the wherein the tubing string is a drillstring and wherein the tubular housing includes an upper driver end and a lower driven end, wherein the upper driver end is coupled with the drillstring and fixed with respect to the pipe and the lower driven end engages and disengages with the pipe.

19. A method for limiting torque in a well system, the method comprising:
running a downhole torque limiter into a wellbore, the downhole torque limiter coupled with at least a tubing string and including:
a tubular housing;
a pipe positioned within the tubular housing;
one or more clutch mechanisms positioned between the pipe and the tubular housing, the one or more clutch mechanisms configured to move between an engaged state to fix the tubular housing relative to the pipe and a disengaged state to allow with the tubular housing to rotate relative to the pipe; and
