ABSTRACT:
A hydraulic setting tool for packers. The setting tool comprises a case with a ball valve therein, a bypass passageway for bypassing around the ball valve when the ball valve is in a closed position, a fill valve for closing the bypass passageway when desired, and a packer setting sleeve for hydraulically setting a packer attached below the setting tool. The fill valve is preferably characterized by a sliding sleeve valve annularly disposed on a stationary mandrel in the case and is movable in response to a pressure in the tool. The packer setting sleeve is attached to a setting piston which may be actuated in response to a first differential pressure between the tool string and a well annulus. A slidable mandrel is provided in operative association with the ball valve and is movable in response to a second differential pressure between the well annulus and the tool string. The second differential pressure also acts to raise the setting piston and setting sleeve to a retracted position spaced away from the packer. A method of positioning and setting a packer using the setting tool is also disclosed.
