Abstract

An apparatus for axially displacing a downhole tool or a tubing string in a well bore equipped with a wellhead, the downhole tool being supported by a tubing string in the well which includes a telescoping joint to permit the axial displacement of the tool is described. The apparatus includes a lifting mechanism such as a hydraulic cylinder or a mechanical jack which is connected to a lift rod string. The lift rod string engages a latch point in the telescoping joint to support the weight of the tubing string and the downhole tool. The apparatus permits the downhole tool to be displaced within a range constrained by the length of the telescoping joint. The apparatus further preferably includes a motor for rotating the lift rod string to permit downhole packers or anchors to be released by rotational movement of the tubing string. The apparatus also preferably includes support legs to bear a portion of the weight of a suspended tubing string in order to reduce tension on the wellhead components. The advantage is a simple, light weight, versatile lifting apparatus which is inexpensively manufactured and readily transported from one wellhead to another.
