摘要： A liner hanger running system including a liner hanger having a body including a wall defined by an outer surface and an inner surface. The body includes an opening that extends through the outer surface and the inner surface. A piston housing including a wall portion defined by an outer surface portion and an inner surface portion is spaced from the outer surface of the body to define a piston Chamber exposed to the opening. A piston is arranged in the piston chamber. A liner hanger running tool including a dog key extends into the opening and engages the piston. The dog key is selectively shiftable relative to the liner hanger to release the piston and expose the opening to a setting pressure.

摘要： An apparatus for retaining and releasing a pump down plug includes an outer housing having a recess and a shifting sleeve that contains the pump down plug and is disposed within the outer housing. The shifting sleeve is configured to slide within the outer housing. The apparatus also includes a retaining element configured to engage the pump down plug to retain the pump down plug, the retaining element being restrained from outward movement by the outer housing in a first position of the shifting sleeve, wherein sliding the shifting sleeve into a second position results in outward movement of the retaining element into the recess to release the pump down plug.
