摘要： Methods and apparatus for shaping pipes, tubes, liners, or casing at downhole locations in wells. Use is made of rollers bearing radially outwards against the inside wall of the pipe (etc.), the rollers being rolled around the pipe to cause outward plastic deformation which expands and shapes the pipe to a desired profile. Where one pipe is inside another, the two pipes can be joined without separate components (except optional seals). Landing nipples and liner hangers can be formed in situ. Valves can be deployed to a selected downhole location and there sealed to the casing or liner without separate packers. Casing can be deployed downhole in reduced-diameter lengths and then expanded to case a well without requiring larger diameter bores and causing further uphole. The invention enables simplified downhole working, and enables a well to be drilled & produced with the minimum downhole bore throughout its depth, obviating the need for large bores. When expanding lengths of casing, the casing does not need to be anchored to made pressure-tight. The profiling/expansion tools of the invention can be deployed downhole on coiled tubing, and operated without high tensile loads on the coiled tubing.

摘要翻译： 用于在井中的井下位置成形管，管，衬套或套管的方法和装置。 使用的是由径向向外的滚筒对着管子（等）的内壁，辊子围绕着管子滚动，引起向外的塑性变形，从而使管子膨胀并变形成所需的轮廓。 如果一个管道在另一个管道内，则两个管道可以没有单独的部件（除了可选的密封件）连接。 可以在原地形成着陆乳头和衬垫衣架。 阀可以部署到选定的井下位置，并且在没有单独的封隔器的情况下密封到套管或衬管。 套管可以以直径较小的长度部署在井下，然后扩展到井口，不需要较大直径的孔并且进一步向上钻孔。 本发明能够简化井下作业，并且能够在整个深度上钻井和生产最小的井下孔，从而避免了对大孔的需要。 当扩大套管长度时，套管不需要锚固就可制成压力。 本发明的型材/膨胀工具可以在连续油管上部署在井下，并且在连续油管上没有高拉伸载荷下操作。
