    • 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).
    • 钻井系统包括多功能副(32),其被配置为联接到钻机(10)的顶部驱动器(28)并且被配置为联接到管状(44),以便选择性地将转矩从 顶部驱动器(28)连接到管状(44)。 多功能副(32)包括转矩检测部件(70),其被配置为经由多功能副部件(32)测量从顶部驱动器(28)提供给管状部件(44)的扭矩;离合器(74) ,其配置成当所述离合器(74)被释放时暂停从所述顶部驱动器(28)到所述管状物(44)的转矩;以及离合器致动器,其通信地联接到所述转矩检测部件(70)并且被构造成释放所述离合器 当由扭矩感测部件(70)测得的扭矩大于阈值扭矩值时, 多功能副(32)还包括补偿器(76),其被配置为使得多功能副(32)能够相对于顶部驱动器(28)在轴向方向上移动管状件(44)。
