    摘要： An annular pressure activated downhole tool has a housing including an outer surface, an inner surface defining a passage, an annular projection projecting into the passage from the inner surface, and an opening. A mandrel extends into the passage. The mandrel has a first end and a second end. A power spring support is detachably connected to the second end of the mandrel in the passage. A power spring is arranged about the mandrel and extends between the power spring support and the annular projection. A trigger housing is arranged in one of the mandrel and the power spring support. A trigger arranged in the trigger housing selectively engages with the inner surface. The trigger is operable to disengage from the inner surface of the housing, releasing the power spring, and shifting the mandrel along the passage when exposed to a selected annular pressure.

    摘要： An anchor setting system having redundant setting methodologies including a housing having an internal chamber. The housing has an outer surface, an inner surface, a first end, and a second end. A slip is shiftably mounted to the outer surface of the housing. A piston assembly including a piston element is arranged in the housing. The piston element includes a conduit and is shiftably mounted in the internal chamber. An activator is mounted to the piston assembly. The activator selectively shifts the slip axially along the housing in response to movement of the piston element.

    摘要： A method of activating an anchor with an anchor activation system including a housing having an outer surface and an inner surface defining an internal chamber includes introducing a first activation force to a trigger comprising a piston arranged in a piston cylinder extending radially through the outer surface to the internal chamber, sensing that the first activation force did not activate the anchor, and introducing a second activation force to the trigger without reconfiguring the anchor activation system to break a shear element retaining the piston with the first activation to release the piston and activate the anchor

    摘要： An anchor activation system including a housing having an outer surface, an inner surface defining an internal chamber, a first end, and a second end. A slip is shiftably mounted to the outer surface of the housing. The anchor activation system also includes a piston assembly and an activator mounted to the piston assembly. The activator selectively shifts the slip axially along the housing. A biasing member is arranged between the second end and the activator. A trigger is operable to selectively release the piston assembly.
