    • A method of expanding a tubular element is provided, the tubular element having a first portion to be expanded to a first inner diameter and a second portion to be expanded to a second inner diameter larger than the first inner diameter. The method comprising: a) arranging an expandable sleeve of selected wall thickness in said second tubular element portion; b) positioning an expander in the tubular element; c) operating the expander so as to expand said first tubular element portion to the first inner diameter, and operating the expander so as to expand the sleeve to an inner diameter substantially equal to the second inner diameter minus double the wall thickness of the sleeve; and d) retrieving the sleeve from the tubular element.
    • 提供了一种使管状元件膨胀的方法,该管状元件具有第一部分,该第一部分被扩张至第一内径,第二部分被扩张至比第一内径大的第二内径。 该方法包括:a)在所述第二管状元件部分中布置所选壁厚的可膨胀套筒; b)将膨胀机定位在管状元件中; c)操作所述膨胀机,以使所述第一管状元件部分膨胀至所述第一内径,并操作所述膨胀器以使所述套筒膨胀至基本上等于所述第二内径的内径减去所述套筒的壁厚的两倍; 以及d)从所述管状元件取回所述套筒。

    • An assembly for use in a wellbore formed in an earth formation, comprising an expandable tubular element and an outer structure having first and second portions arranged at a distance from each other, the portions being restrained to the tubular element in a manner that the distance changes as a result of radial expansion of the tubular element, the outer structure further having a third portion arranged to move radially outward upon said change in distance between the first and second portions, wherein said radially outward movement of the third portion is larger than radially outward movement of the tubular element as a result of radial expansion of the tubular element.
    • 一种用于在地层中形成的井眼中的组件,包括可膨胀的管状元件和外部结构,所述外部结构具有彼此间隔一定距离的第一和第二部分,所述部分以这样的方式被限制到所述管状元件 由于管状元件的径向膨胀,外部结构还具有第三部分,该第三部分布置成在所述第一和第二部分之间的距离变化时沿径向向外移动,其中所述第三部分的径向向外的运动大于径向向外的 作为管状元件的径向膨胀的结果,管状元件的移动。
