Abstract
A drill string system includes a drill bit disposed at a distal end of a drill string. A clutch is coupled with the drill bit. A mud motor is coupled to the clutch, and the mud motor is operable to receive a drilling fluid therein and transfer torque to the drill bit through the clutch. The clutch disengages upon application of a torque exceeding a predetermined threshold.
Claims20
A drill string system comprising:
- a drill bit disposed at a distal end of a drill string;
- a clutch coupled with the drill bit;
- and
- a mud motor coupled to the clutch, the mud motor operable to receive a drilling fluid therein and transfer torque to the drill bit through the clutch,
- wherein the clutch disengages upon application of a torque exceeding a predetermined threshold.
A mud motor assembly comprising:
- a mud motor;
- and
- a clutch operably coupled with the mud motor and operable to be coupled with a drill bit, wherein the clutch operably disengages upon application of a torque exceeding a predetermined threshold.
The assembly of claim 15, wherein the stator has a plurality of lobes operable to rotationally receive a corresponding lobe on the rotor during rotation of the rotor within the stator.
A method comprising:
- disposing a drill string in a wellbore within a subterranean environment, the drill string having a drill bit, a clutch, and a mud motor;
- engaging the drill bit with at least a portion of the subterranean formation;
- receiving a drilling fluid in the mud motor;
- generating a torque in the mud motor;
- transferring the torque from the mud motor to the drill bit using the clutch;
- and
- disengaging the clutch if the torque on the mud motor exceeds a predetermined threshold.
