Method of controlling torque applied to a tubular connection

摘要

Embodiments of the present invention generally relate to a method for controlling the torque applied to a tubular connection. In one embodiment, a method of connecting a first threaded tubular to a second threaded tubular supported by a spider on a drilling rig includes engaging the first threaded tubular with the second threaded tubular; making up the connection by rotating the first tubular using a top drive; and controlling unwinding of the first tubular after the connection is made up.
