Abstract
A tree running tool is provided which has a means for actuating a latch for latching a side valve tree to a wellhead. Also disclosed is a tree running tool having an external axially movable actuator, preferably in the form of a sliding piston sleeve which is capable of exerting great forces. Also disclosed is a tree running tool having an external connector unit for connecting the tree running tool to a side valve tree. The connector unit is preferably mounted to the sliding piston sleeve and is for axially mechanically connecting the tree running tool to a linkage extending upwardly from the side valve tree.
Claims21
A tree running tool having means for actuating a latch for latching a side valve tree to a wellhead, said tree running tool comprising
- a tool body having an upper end, a lower end, and an axial passage extending therethrough;
- a linkage latch for latching the tree running tool to a linkage extending from the side valve tree;
- a mounting means mounted to an outside surface of the tool body for axially moving the linkage latch from a first longitudinal position alongside the tool body to a second longitudinal position alongside the tool body;
- and
- an actuator means mounted to the mounting means for actuating the linkage latch to latch the tree running tool to the linkage extending from the side valve tree.
A tree running tool having an external axially movable actuator, said tree running tool comprising
- a tool body having an upper end, a lower end, and an axial passage extending therethrough, said tool body having a generally cylindrical outside surface;
- a sleeve having a generally cylindrical inside surface mounted to the generally cylindrical outside surface of the tool body, the generally cylindrical inside surface of the sleeve being spaced concentrically apart from the generally cylindrical outside surface of the tool body to form a chamber of annular cross section;
- means defining a closure for the upper end of the chamber;
- means defining a closure for the lower end of the chamber;
- means defining a flange for separating the chamber into an upper portion and a lower portion;
- means defining a fluid passage to the upper chamber;
- and
- means defining a fluid passage to the lower chamber.
A tree running tool having an external connector unit for connecting the tree running tool to a side valve tree, said tree running tool comprising:
- a tool body having an upper end, a lower end, and an axial passage extending therethrough, said tool body having a generally cylindrical outside surface;
- a hydraulic actuator mounted to the generally cylindrical outside surface of the tree body for axial movement with respect to the tree body from a first longitudinal position to a second longitudinal position;
- and
- a connector unit mounted to the hydraulic actuator for axially connecting to a linkage extending upwardly from the side valve tree.
