摘要: A method of expanding tubing comprises locating an expansion tool in a section of tubing to be expanded, applying a fluid pressure to the tubing to create a fluid pressure expansion force and induce a hoop stress in the tubing, and applying a mechanical expansion force to the tubing via the expansion tool. The combined fluid pressure expansion force and mechanical expansion force is selected to be sufficient to induce expansion of the tubing.

摘要: A traction apparatus (1) for propulsion along a bore comprises first and second traction members (6) having outwardly extending legs (14). A propulsion system for operating the traction members (6) comprises a turbine-driven shaft (7) which drives the traction members (6) by way of bearing members (15). In a first phase, one of the legs of the first traction member is moved in one direction whilst in contact with the traction surface to impart the propulsion force at the same time as one of the legs of the second traction member is moved in opposite direction whilst out of contact. In a second phase one of the legs of the second traction member is moved in said one direction whilst in contact with the traction surface to impart the propulsion force at the same time as one of the legs of the first traction member is moved in opposite direction whilst out of contact.

摘要: A method of coupling first and second tubulars (12,14) comprises providing a first tubular having a first yield strength and a second tubular having a higher second yield strength. A portion of the first tubular is located within and overlapping a portion of the second tubular and the first tubular is expanded sufficient to expand the second tubular, at least the first tubular being expanded beyond its yield point. Following expansion, a degree of elastic contraction of the tubulars is permitted, sufficient to provide interference between the tubulars.

摘要: A method and apparatus is provided for drilling and lining a wellbore in one downhole trip. The method comprises mounting a drill bit on a drill string including a section of expandable tubing and providing a tubing expander in the string, then rotating the drill bit and advancing the drill string through a bore, then passing the expander through the expandable tubing to expand the tubing, wherein the expandable tubing is deformed by compressive plastic deformation of the tubing with a localised reduction in wall thickness, resulting in a subsequent increase in tubing diameter, and then retrieving the drill bit from the bore through the expanded tubing. The apparatus comprises a drill string including a section of expandable tubing, a drill bit mounted on the string, and a tubing expander mounted on the string, wherein the expandable tubing is deformed by compressive plastic deformation of the tubing with a localised reduction in wall thickness, resulting in a subsequent increase in tubing diameter and wherein the drill bit may be retrieved through the expanded tubing.
