OSTI ID:6830776
This patent describes a hydraulically set packer mechanism for use in a subterranean well. It comprises: a tubular housing carryable in the well on a tubular conduit and telescopically positionable within a second conduit in the well; a seal assembly disposed around the housing and carried in the well in initially retracted position and activatable into expended position within the well to sealing securement relative to the inner wall of the second conduit; anchoring means for securing the packer mechanism in position within the second conduit and activatable to securing condition to resist movement of the packer mechanism relative to the second conduit in at least one direction; first and second cylindrically members of the tubular housing movable in a first direction to actuate one of the seal assembly and the anchoring means into engagement with the second conduit; and primary and secondary piston means carried within the cylindrical members and tandemly arranged for movement in a second direction to activate the other of the seal assembly and the anchoring means and responsive to pressure introduced through the tubular conduit for the actuation.
