Abstract

A hydraulic setting tool for setting a packer with a sliding valve therein in an operating position in a well bore. The setting tool comprises an outer housing portion slidably disposed with respect to an inner mandrel portion. A piston is connected to the outer housing portion and slidable with respect to the inner portion. The piston is responsive to tubing pressure for setting the packer. A locking dog is provided for locking said piston against further movement after setting of the packer. An actuating mandrel forms a part of the inner mandrel portion and is adapted for engaging a valve in the packer. Longitudinal movement of the tool string allows selective opening and closing of the valve in the packer.
