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:
A wellbore casing formed by extruding a tubular liner off of a mandrel. The tubular liner and mandrel are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with an existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the mandrel and into the annular region between the tubular liner and the new section of the wellbore. The inner and outer regions of the tubular liner are then fluidicly isolated. A non hardenable fluidic material is then injected into a portion of an interior region of the tubular liner to pressurize the portion of the interior region of the tubular liner below the mandrel. The tubular liner is then extruded off of the mandrel.

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.
摘要:
A tubular sleeve overlaps the threaded connection between a pair of adjacent tubular members that are to receive an expansion device for radial expansion and plastic deformation of the threaded tubular connection.
摘要:
A mono-diameter wellbore casing is formed by radially expanding a first tubular liner off of a mandrel into contact with a second tubular liner. The first and second tubular liners are positioned within the wellbore in an overlapping relationship. The overlapping portions of the tubular liners include thin wall portions with compressible annular members that are expanded into contact with each other.
摘要:
An apparatus for radially expanding and plastically deforming a tubular member includes a support member comprising a fluid passage, an expansion device for radially expanding and plastically deforming the tubular member movably coupled to the support member for longitudinal displacement relative to the support member, a plurality of pressure chambers defined by and positioned between the support member and the expansion device fluidicly coupled to the first fluid passage, and one or more releasable supports coupled to the support member adapted to support the tubular member positioned below the expansion device.
摘要:
First and second members, representatively first and second portions of a collet assembly, are removably coupled to one another by aligning slots in the first member with slots in the second members to form opposing slot pairs into which coupling members are inserted in first directions. The inserted coupling members are removed from the slot pairs, in second directions opposite from the first directions, in response to the generation of a fluid pressure.
