Abstract: A tubing rotator and a drive therefor. The tubing rotator includes an input shaft to a tubing rotator gear; an electric motor including an output shaft; and a plurality of worm drives arranged in series and configured to (i) receive input from the electric motor and (ii) output torque to the input shaft of the tubing rotator. The worm drives may be identical speed reducers, such as with an input to output reduction ratio of from 25:1 to 40:1.
Abstract: Disclosed herein is a tubing string anchor for resisting angular rotation of the tubing string, as when undergoing pumping through the string. The anchor includes a plurality of anchoring members each rotatable about a fulcrum between a locking position and a non-locking position. The anchor housing has a groove formed between adjacent anchoring members through which a string may be run to access below the anchor when the anchor is installed.
