Actuation and Release Tool for Subterranean Tools |
摘要 |
An actuator for a subterranean tool is releasably retained by a collet. The actuation system features opposing actuation pistons with ports communicating to the tubing. The spaced ports are sequentially straddled for initial setting and a subsequent release using a predetermined applied pressure. The applied pressure overcomes the retaining force of the collet and actuates a one of two opposed pistons to set the tool, which is preferably a liner hanger. Upon shifting the actuation tool to communication to another port leading to an actuating piston pushing in another direction with applied pressure releases the tool and re-latches a retaining collet. The tool can be set, released and repositioned for another cycle in the same trip in the hole. |
