摘要:
An apparatus and method for coupling a tubular member to a preexisting structure. The tubular member is anchored to the preexisting structure and an expansion member is displaced relative to the tubular member to radially expand the tubular member.
摘要:
A mono-diameter wellbore casing. The mono-diameter wellbore casing is formed by plastically deforming and radially expanding a first tubular member within a wellbore. A second tubular member is then plastically deformed and radially expanded in overlapping relation to the first tubular member. The second tubular member and the overlapping portion of the first tubular member are then radially expanded again.
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 apparatus and method for coupling a tubular member to a preexisting structure. The tubular member is anchored to the preexisting structure and an expansion member is pulled through the tubular member to radially expand the tubular member.
摘要:
A method for expanding a tubular member in a wellbore includes applying a downward force to an expansion cone through a work string to anchor the tubular member in the wellbore and pulling upwards on the expansion cone with the work string to expand the tubular member. The expansion cone is disposed in a launcher portion connected to the tubular member being expanded.
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.
