摘要： A method and apparatus for a pressure relief valve assembly. The valve assembly may be coupled to one or more casings and/or tubular members to control fluid communication therebetween. The valve assembly is a one-way valve assembly that relieves pressure within an annulus formed between adjacent casings and/or tubular members to prevent burst or collapse of the casings and/or tubular members. The valve assembly is resettable downhole.

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.

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.
摘要翻译：一种在井眼中的限制下方扩张管状的方法和装置。可膨胀管可以包括具有第一壁厚的第一端，具有第二壁厚的第二端和设置在第一和第二端之间的中间部分，并且具有小于第一和第二壁厚度的第三壁厚度。第一端和第二端可以包括沿着端部的长度设置的一个或多个槽。用于在管井下方将管状物膨胀的方法可包括将管状件运行通过限制器，其中管状件包括第一端和第二端，每个端部的壁厚大于中间部分的壁厚，结束。该方法可以包括使管状物膨胀，其中，膨胀管的第一和第二端的外径大于中间部分的外径。
