EXPANDING DOWNHOLE TUBING BY COMPRESSION |
摘要 |
A method of expanding tubing downhole comprises providing a section of expandable tubing of a first diameter, and axially compressing the tubing to induce buckling, such that the buckled portion describes a larger second diameter. The resulting diametric expansion may be utilised to anchor or seal the tubing within a larger bore. The buckled portion may be used to anchor the tubing within the wellbore prior to expansion of the length of the tubing into the wellbore.</ SDOAB>
