发明名称 Method of hydraulically actuating and mechanically activating a downhole mechanical apparatus
摘要 The present invention generally relates to an apparatus and method for operating a tool in a wellbore. In one aspect, the apparatus includes a hydraulically operated tool and a wellbore tubular both in communication with a pressure sensing line. The hydraulically operated tool is responsive to a combination of a fluid pressure in the pressure sensing line and a manipulation of the wellbore tubular, such response causing the tool to operate within the wellbore. In another aspect, the invention provides a method for anchoring a well tool in a wellbore. The method includes the steps of lowering the well tool into the wellbore on a tubular string, flowing fluid through the tubular string to begin anchoring the well tool, and manipulating the tubular string to complete the anchoring of the well tool.
