案例分享 Drilling with Liner Rescues Well in Deepwater Gulf of Mexico and Saves at Least USD 20 Million
Eliminating a dedicated liner run through a high-loss gassy salt zone reduced rig time by multiple days.

High-capacity hydraulic rotating liner hanger
Deploy heavy liners in drilldown applications
Reduce costs and time by deploying heavy and long liners in drilldown applications with the premium high-capacity hydraulic rotating liner hanger (HCHR). This hydraulic-set, hydraulic-release hanger is engineered for deepwater and deep land and offshore wells, even in HPHT conditions, with a slip-cone design that distributes axial and radial loading through the hanger body and provides increased hanging capacity over cone-type hangers.
Minimize risks of premature setting
An antipreset mechanism prevents the hanger from being set before the hydraulic setting mechanism is activated, and fully pocketed slips reduce running and rotating interference in drilldown applications. When enough pressure has been applied to the system and the slips have been set, the high-performance bearing enables rotation during cementing to improve cement integrity.
