Abstract
An anchoring apparatus for securing a production tubing string against axial movement in a subterranean well is disclosed. The anchoring apparatus can be employed with a conventional sucker rod pumping apparatus transporting fluids through the production tubing. A separate injection line is attached to the exterior of the production tubing and treating fluids are injected therethrough. A conduit which can be connected to the separate injection line extends along the exterior of the inner body of the anchoring apparatus in an axially extending groove and extends through encircling anchoring slips which are expanded by rotational movement of the production tubing and of the body of the anchoring apparatus.
