发明名称 RUNNING TOOL WITH OVERSHOT SLEEVE
摘要 A running tool with an overshot sleeve is provided. In one embodiment, a system includes a running tool and an overshot sleeve including a first portion threaded onto the running tool and a second portion. The first portion and the second portion are connected together in a manner that allows the first portion and the second portion to rotate with respect to one another. The second portion of the sleeve can engage an additional component, such as a casing hanger, and the running tool and the overshot sleeve can be configured to selectively convert rotation of the running tool into axial motion of the overshot sleeve with respect to the running tool. Additional systems, devices, and methods are also disclosed.

主权项 1. A method comprising: inserting a running tool connected to a casing hanger and to a sleeve into a wellhead, wherein the running tool is connected to the casing hanger and to the sleeve such that, upon rotation of the running tool, torque is transmitted from the running tool to the casing hanger via the sleeve to cause the casing hanger and the sleeve to rotate synchronously with the running tool; engaging a first portion of the sleeve so as to inhibit rotation of the first portion of the sleeve while permitting rotation of a second portion of the sleeve with the running tool and the casing hanger; rotating the running tool and the second portion of the sleeve while inhibiting rotation of the first portion of the sleeve to cause the sleeve to move axially along the running tool and to disengage from the casing hanger such that torque is no longer transmitted from the running tool to the casing hanger via the sleeve; and once the sleeve has disengaged from the casing hanger, rotating the running tool within the wellhead to disconnect the running tool from the casing hanger.
