摘要:
An apparatus for expanding a tubular member comprising a support member, an expansion device for radially expanding the tubular member movably coupled to the support member for longitudinal displacement relative to the support member, at least one pressure chamber defined by and positioned between the support member and expansion device, and one or more releasable supports coupled to the support member adapted to support the tubular member, wherein the releasable supports are positioned above the expansion device.

摘要:
A method of creating a casing in a borehole located in a subterranean formation including: supporting a tubular liner and an expansion device in the borehole using a support member; injecting fluidic material into the borehole; pressurizing an interior region of the expansion device; displacing a portion of the expansion device relative to the support member and the tubular liner in the longitudinal direction; and radially expanding the tubular liner.
摘要:
An apparatus for radially expanding and plastically deforming a tubular member includes a support member with a fluid passage. A mandrel is movably coupled to the support member and includes an expansion cone operable to radially expand and plastically deform the tubular member when moved relative to the tubular member. A pressure chamber is positioned between the support member and the mandrel, and the pressure chamber is fluidicly coupled to the fluid passage. A releasable support is coupled to the support member and operable to selectively couple the support member to the tubular member.
