摘要： A system for use in a well includes a liner hanger including a mandrel, a cone mounted about the mandrel, the cone having tapered slips, a plurality of tapered slips slidably received in the tapered slots, each tapered slip of the plurality of tapered slips comprising a plurality of teeth, wherein each tapered slip of the plurality of tapered slips and the corresponding tapered slot includes a setting ramp, and a loading ramp separate from the setting ramp, and an actuator mounted about the mandrel to selectively shift the plurality of tapered slips between a radially contracted position and a radially expanded, set position.

摘要： A technique facilitates deploying and setting a liner hanger assembly while securely retaining liner hanger slips during running-in-hole. The liner hanger assembly may comprise a variety of components such as a mandrel, a cone, a plurality of slips, a retention ring, and an actuator. The slips may each be configured with an upper retention end and a lower retention end having a plurality of angles which interlock with corresponding angles of the cone and the retention ring. Additionally, a portion of the actuator may be sized to slide over an axial end of the retention ring to prevent inadvertent decoupling of the slips after installing the slips along the exterior of the cone.
