APPARATUS AND METHODS FOR APPLYING TORQUE TO A SUCKER ROD CONNECTION

摘要

An apparatus usable to apply torque to a sucker rod connection is described herein. The apparatus includes an insert for installation within a tong device configured to provide torque to a tubular, the insert adapting the tong to engage and apply torque to a sucker rod segment. The insert can include a flange secured to the tong device, a tubular body extending through the opening of the tong device and engaging gripping members of the tong, and an engagement member having a slot sized to engage a sucker rod segment. A back-up tong device can be used to retain a lower sucker rod segment while an upper sucker rod segment is torqued by the tong device. The back-up tong device and/or the tong and insert can be pivotably or rotatably movable for engaging a lower sucker rod segment that is not in rotational alignment with the upper sucker rod segment.
