20140338891 | Slip with Altering Load Distribution Feature - A liner hanger has slips held by a slip body. A potential energy force to move the slips axially when the hanger is in position is selectively released. The slips move axially and radially outwardly guided on opposed edges by the slip body. The slip faces have wickers that dig into the surrounding casing that will support a liner string off the slips. Weight is set down to bring the housing into contact with the top of the slips that are already engaged to the surrounding casing. The nature of the loading between the slips and the casing changes from a radial reaction force from the casing going into the slip and then distributed circumferentially to the slip housing to an essentially axial loading of the slip housing down onto the slip that has penetrated the casing with an opposite reaction force in the casing wall. | 11-20-2014 |
