发明名称 Shear release packer and method of transferring the load path therein
摘要 A shear release packer that includes at least one sealing element, at least one slip, and at least a lower shear nut. In order to release the packer, the lower shear nut is sheared enabling the at least one sealing element to de-energize and the at least one slip to disengage the casing. When set, the packer is constructed to that the lower shear nut is isolated from the load path generated by the forces acting on the at least one sealing element. The load path travels from the at least one sealing element to the at least one slip without having to travel through the lower shear nut.
