    摘要: The present invention generally relates to a cone system having a cone segment capable of deflecting in response to a restriction or obstruction encountered while expanding a tubular. In one aspect, an expansion cone system is provided. The expansion cone system includes a mandrel and two or more pockets disposed circumferentially around the mandrel. Each pocket is at least partially defined by a fin member. The expansion cone system further includes a cone segment coupled to each pocket. Additionally, the expansion cone system includes a biasing member disposed between the mandrel and the respective cone segment. In another aspect, a method of expanding a wellbore tubular is provided.

    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.

    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 one or more grooves disposed along a length of the ends. 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: The present invention generally relates to a swage assembly that is movable from a compliant configuration having a first shape to a substantially non-compliant configuration having a second shape. In one aspect, an expansion swage for expanding a wellbore tubular is provided. The expansion swage includes a body and a solid cone disposed on the body. The expansion swage further includes a deformable cone disposed on the body, wherein the solid cone is made from a first material and the deformable cone is made from a second material and wherein the deformable cone is movable relative to the body when the expansion swage is in a compliant configuration. In another aspect, a method of expanding a wellbore tubular is provided.
