    摘要: An apparatus (10) includes a traction member in the form of a roller (24) configured for mounting on a body (12) so as to permit rotation of the roller (24) relative to the body (12). The roller (24) is mountable on the body (12) so as to define a skew angle relative to a longitudinal axis (26) of the body (12). In use, the roller (24) engages a wall of a borehole or bore-lining tubular and the roller (24) urges the apparatus (10) along the wall of the borehole or bore-lining tubular on rotation of the as the roller (24) rotates on the body (12).

    摘要: A method of lining a drilled bore comprises running a tubular into a drilled bore and then corrugating the tubular in the bore. The tubular may also be expanded in the bore. In other aspects of the invention the tubular is corrugated prior to running into the bore and may be rotated as it is run into the bore.

    摘要: A method of lining and drilling a bore (10) comprises the steps of mounting a first section of bore-lining tubing (20) on the lower end portion of a drill string (18). The method also includes running the drill string and tubing into a bore having an unlined section and an existing tubing lined section, locating the first tubing section (20) in the unlined section, uncoupling the first tubing section (20) from the drill string (18), and drilling the bore beyond the first tubing section.

    摘要: 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.
