    摘要： An apparatus for radially expanding atubular member that includes a support member having an exterior surface, a tubular member having an interior surface coupled to the support member, an annular expansion cone having a continuous outer surface movably coupled to the exterior surface of the support member and the interior surface of the tubular member for radially expanding the tubular member, and a preload assembly coupled to the support member for applying an axial force from the support member to the annular expansion cone to preload the annular expansion cone against the tubular member. The preload assembly including a compressed spring coupled to the support member for applying the axial force to the annular expansion cone.

    摘要： An apparatus and method for forming a wellbore casing. An annular piston is displaced in the axial direction by pressurizing an annular piston chamber. The axial displacement of the piston radially expands a tubular member into contact with a preexisting tubular member. The radially expanded liner hanger is then decoupled from the apparatus.
