摘要： A method of increasing the collapse resistance of a tubular comprises locating a tool having at least one, and typically three, bearing members within a tubular. The bearing members are positioned in engagement with a wall of the tubular to apply a radial force to a discrete zone of the wall. This radial force is then applied to further discrete zones of the wall, the level of radial force being selected such that the collapse resistance of the tubular is increased.

摘要： A method of expanding tubing such as a section of casing includes locating the casing in a bore and expanding a portion of the casing to engage the bore wall using an expansion tool having at least one radially movable expansion member. The expansion member may be in the form of a roller of a rotary expander. The method additionally includes subsequently expanding a further portion of the casing by advancing a cone expander through the casing.

摘要： The present invention provides methods and apparatus for expanding a first, smaller diameter tubular into frictional contact with a second, larger diameter tubular or wellbore. In an embodiment, annular formations formed on an inner surface of a split ring engage an outer surface of the smaller tubular. In one aspect, the smaller diameter tubular is provided with an annular recess there around, the annular recess including recessed grooves formed there around. Therefore, the split ring is disposable within the annular recess and the annular formations formed on the split ring are constructed and arranged to fit within the recessed grooves of the annular recess of the tubular. An outer surface of the split ring is provided with teeth or some other grip-enhancing material or formation. The split ring also includes a split portion permitting the ring to expand in diameter as that portion of the tubular is expanded in diameter.
