摘要:
A tool for expanding a liner in a wellbore includes a cone assembly that is moveable between a retracted position and an extended position. The tool also includes a jack assembly that is operable by fluid pressure to move the cone assembly from the retracted position to the extended position. The fluid pressure is also applied to expansion cup seals to generate axial load that urges the cone assembly to move through the expandable liner and radially expand of the expandable liner. A latch assembly axially fixes the liner while the cone assembly moves to the extended position. Once the cone assembly is fully moved to the extended position, the latch assembly releases the liner, allowing the cone assembly to move through the liner and radially expand the liner.
