System and method with torque control from top drive

摘要

A drilling system includes a multi-function sub (32) configured to be coupled to a top drive (28) of a drilling rig (10) and configured to be coupled to a tubular (44) in order to selectively transfer a torque from the top drive (28) to the tubular (44). The multi-function sub (32) includes a torque sensing component (70) configured to measure the torque provided from the top drive (28) to the tubular (44) via the multi-function sub (32), a clutch (74) configured to suspend a transfer of torque from the top drive (28) to the tubular (44) when the clutch (74) is released, and a clutch actuator communicatively coupled to the torque sensing component (70) and configured to release the clutch (74) when the torque measured by the torque sensing component (70) is greater than a threshold torque value. The multi-function sub (32) also includes a compensator (76) configured to enable the multi-function sub (32) to move the tubular (44) in an axial direction relative to the top drive (28).
