摘要
Methods for making a threaded connection between an upper tubular and a lower tubular using an oilfield tubular spinner and a torque wrench, including holding the lower tubular with the torque wrench, frictionally engaging the upper tubular with the tubular spinner, operating a motor of the tubular spinner to spin-in and shoulder-up a tubular connection between the upper tubular and the lower tubular, establishing a threshold hydraulic system pressure that indicates a shouldered-up condition, monitoring, with a detection system, a hydraulic system pressure of the motor during spin-in and shoulder-up, and maintaining the threshold hydraulic system pressure to operate the motor for a selected period of time after the threshold hydraulic system pressure is reached. An oilfield tubular spinner for an oilfield tubular wrench is also provided.
