    • An apparatus and method for expanding a lower string of casing into frictional contact with an upper string of casing, and thereby hanging the lower string of casing onto the upper string of casing is provided. The apparatus essentially defines a lower string of casing having a scribe placed into the top end thereof. The lower string of casing is run into the wellbore, and positioned so that the top end overlaps with the bottom end of an upper string of casing already cemented into the wellbore. The top end of the lower casing string is expanded below the depth of the scribe into frictional contact with the upper string of casing. At the same time, or shortly thereafter, the top end of the upper string of casing is expanded. As the portion of the lower casing string having the scribe is expanded, the casing severs into upper and lower portions. The upper portion can then be removed from the wellbore, leaving a lower string of casing expanded into frictional engagement with an upper string of casing.
    • 提供了一种用于使下部套管膨胀成与上部套管摩擦接触并由此将下部套管悬挂在上部套管上的装置和方法。 该装置基本上限定了具有放置在其顶端中的划线的下部套管。 套管的下部套管进入井眼,并且定位成使得顶端与已经胶合到井眼中的上部套管的底端重叠。 下套管柱的顶端在划片的深度下方扩展成与上部套管摩擦接触。 同时,或之后不久,上部套管的顶端扩大。 随着具有划片的下壳体串的部分膨胀,壳体切换成上部和下部。 然后可以从井筒中取出上部部分,留下下部套管膨胀成与上部套管摩擦接合。

    • A method of supporting a tubular within a bore including the steps of at least partially expanding a sleeve into contact with a bore wall to secure the sleeve within the bore, and engaging a portion of the tubular to be supported with the sleeve to provide hanging support for the tubular. In one embodiment, the sleeve is expanded by engagement with the tubular. In another embodiment, the sleeve is initially expanded using a roller expansion tool, with further expansion being achieved by way of engagement of the tubular with the sleeve.An apparatus for supporting a tubular within a bore in one embodiment comprises an expandable sleeve having a first surface and being adapted to be expanded into contact with a bore wall, and a conical portion adapted to be coupled to a tubular, the conical portion having a second surface adapted to engage the first surface of the sleeve.
