ABSTRACT:
A method of and apparatus for setting a mechanical liner hanger inside of a well conduit by right-hand or clockwise rotation and without downward movement. The hanger includes a mandrel having an annular cone and a lug. A movable cage telescopically and rotatably mounted on the mandrel includes slips, bow springs and a right-hand downwardly extending and downwardly directed spiral surface. A hanger is moved downhole with the lug engaging the cage holding the slips in the retracted position. When the setting location is reached the mandrel is lifted up releasing the cage, and the mandrel is rotated by right-hand rotation moving the lug against the downwardly directed surface of the cage for moving the slips upwardly onto the cone and expanding the slip into a setting engagement with the well conduit. The set hanger may be released by longitudinally raising the mandrel and lug. The liner hanger may be recocked by engaging the downwardly directed surface of the cage with the lug and raising the lug to rotate the cage into a recocking position.
