    摘要: The present invention generally relates to an apparatus and method for expanding an expandable tubular assembly in a borehole. In one aspect, a system for expanding a tubular having an anchor portion in a borehole is provided. The system includes a running tool configured to position the tubular in the borehole. The running tool including a first expander configured to activate the anchor portion by expanding the tubular to a first diameter. The system further includes a second expander configured to expand the tubular to a second larger diameter, wherein the second expander is movable between a retracted position and an expanded position. In another aspect, a method of expanding a tubular having an anchor portion in a borehole is provided.

    摘要: A method and apparatus for expanding a tubular below a restriction in a wellbore. An expandable tubular may comprise a first end having a first wall thickness, a second end having a second wall thickness, and a middle section disposed between the first and second ends and having a third wall thickness that is less than the first and second wall thicknesses. The first and second ends may include grooves. A method for expanding a tubular below a restriction in a wellbore may comprise running the tubular past the restriction, wherein the tubular comprises a first end and a second end, each end having a wall thickness greater than a wall thickness of a middle section disposed between the ends. The method may include expanding the tubular, wherein the first and second ends of the expanded tubular have outer diameters greater than the outer diameter of the middle section.

    摘要: Embodiments of the invention generally relate to tools and methods for hanging and/or expanding liner strings. In one embodiment, a method of hanging a liner assembly from a previously installed tubular in a wellbore includes running the liner assembly and a setting tool into the wellbore using a run-in string. The setting tool includes an isolation valve and the liner assembly includes a liner hanger and a liner string. The method further includes sending an instruction signal from the surface to the isolation valve, wherein the isolation valve closes in response to the instruction signal and isolates a setting pressure in the setting tool from the liner string; and increasing fluid pressure in the setting tool, thereby setting the liner hanger.

    摘要: A method and apparatus for completing a well through expansion of tubing enable construction of the well or at least part of the well with a mono-diameter or substantially no inside diameter reduction with subsequent casings/liners. Prior to lining an extended section of the borehole, forming a discrete enlarged portion of the extended section with a relatively larger inner diameter than the remainder of the extended section of the borehole occurs where overlapping tubing sections are to be located. For some embodiments, an open-hole clad expanded in the enlarged portion of the extended section of the borehole provides an inner surface for receiving a bottom of a first expanded liner and optionally a top of a second expanded liner.

    摘要: Methods and apparatus include tubing expanded to create a seal in an annulus surrounding the tubing. The tubing includes a sealing material selected to cause forming of undulations in a diameter of the tubing upon expansion of the tubing. Various factors of the sealing material such as deviations in its thickness influence sealing performance of the tubing with the sealing material.
