摘要： A torque sub for use with a top drive is disclosed. A method of connecting threaded tubular members for use in a wellbore includes operating a top drive. The top drive rotates a first threaded tubular member relative to a second threaded tubular member. The method further includes measuring a torque exerted on the first tubular member by the top drive. The torque is measured using a torque shaft rotationally coupled to the top drive and the first tubular. The torque shaft has a strain gage disposed thereon. The method further includes wirelessly transmitting the measured torque from the torque shaft to a stationary interface; measuring rotation of the first tubular member; compensating the rotation measurement by subtracting a deflection of the top drive and/or the first tubular member; determining acceptability of the threaded connection; and stopping rotation of the first threaded member when the threaded connection is complete or if the threaded connection is unacceptable.
