Abstract

A tubing string rotator is disclosed that comprises an outer housing, a gear mandrel, and a tubing string hanger. The outer housing has an internal bore extending from its upper to its lower. The gear mandrel is received and supported within the bore of the outer housing. The gear mandrel has an internal bore extending from its upper to its lower end. The tubing string hanger has a series of circumferentially positioned generally downwardly oriented teeth and is receivable and suspendable within the internal bore of the gear mandrel such that the teeth on the tubing string hanger engage a series of generally upwardly oriented teeth circumferentially positioned about the internal surface of the gear mandrel. Rotational force applied to the gear mandrel is at least partially transferred to the tubing string hanger through engagement of the teeth on the gear mandrel with the teeth on the hanger causing the tubing string hanger to rotate with the gear mandrel.
