摘要:
An apparatus and method for forming or repairing a wellbore casing, a pipeline, or a structural support. An expandable tubular member is radially expanded and plastically deformed by an expansion cone that is displaced by hydraulic pressure. Before or after the radial expansion of the expandable tubular member, a sliding sleeve valve within the apparatus permit a hardenable fluidic sealing material to be injected into an annulus between the expandable tubular member and a preexisting structure.

摘要:
An apparatus for radially expanding and plastically deforming a tubular member. In some embodiments, the apparatus includes a support member and an adjustable expansion device coupled thereto. The adjustable expansion device includes a tubular support member with a plurality of circumferentially spaced apart inclined surfaces, a plurality of circumferentially spaced apart expansion segments movably coupled to the tubular support member, and an actuator for displacing the expansion segments relative to the tubular support member to thereby displace each of the expansion segments onto corresponding inclined surfaces.
摘要:
An expansion mandrel includes a lubrication system for lubricating the trailing edge portion of the interface between the expansion mandrel and a tubular member during the radial expansion of the tubular member.
摘要:
An expandable threaded connection includes a first tubular member, a second tubular member and a threaded connection for coupling the tubular members that includes one or more sealing members.
