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. A tubular liner and an expansion cone are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with a pre-existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the expansion cone 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 expansion cone. The tubular liner is then extruded off of the expansion cone. The overlapping portion of the pre-existing casing and the tubular liner are then radially expanded using an expansion cone.
摘要:
A method of forming a well bore casing for insertion in a well bore, according to which a first casing section is coupled to a second casing section and a seal is provided between the coupled portions of the sections.
摘要:
A lubrication system for lubricating an interface between one or more expansion surfaces of an expansion device and one or more interior surfaces of a tubular member during a radial expansion of the tubular member using the expansion device.
