Apparatus and method for expanding and fixing a tubular member within another tubular member, a liner or a borehole |
摘要 |
An apparatus for securing a tubular member within a liner or borehole has a seal means connected within the tubular member, and a pressure control device operable to increase the pressure within the tubular member, such that operation of the pressure control means causes the tubular member to move radially outwardly to bear against the inner surface of the liner or borehole wall. Also, a packer for use in a downhole annular space and an isolation plug for plugging a downhole tubular are disclosed.
