Abstract
A liner hanger can include slips configured to anchor the liner hanger in a well, a tubular mandrel, a tubular outer housing outwardly surrounding the mandrel, an engagement member that releasably secures the slips against longitudinal displacement relative to the mandrel, and another engagement member that releasably secures the outer housing against longitudinal displacement relative to the mandrel. A method of setting a liner hanger in a subterranean well can include: applying a differential pressure from an interior to an exterior of the liner hanger, thereby displacing a retainer sleeve relative to a mandrel of the liner hanger, and applying another differential pressure from the interior to the exterior of the liner hanger, thereby displacing an outer housing of the liner hanger relative to the mandrel. The outer housing is prevented from displacing relative to the mandrel until after the retainer sleeve is displaced relative to the mandrel.
