摘要： An apparatus and methods for preventing the accumulation of unwanted materials in an enlarged inner diameter portion of a casing or housing. In one aspect of the invention, a sleeve is disposed in the housing to isolate an annular area defined by the outer surface sleeve and the wall of the enlarged inner diameter portion. The sleeve prevents unwanted materials from being disposed in the annular area. The sleeve can later be expanded into the enlarged inner diameter portion, removed from the wellbore or destroyed. In another aspect of the invention, the sleeve is provided and disposed to cover the enlarged inner diameter portion. By covering the enlarged inner diameter portion, unwanted material is prevented from accumulating at said portion and from interfering with the expansion of the next casing into said portion to form a monobore. The sleeve can be made from materials that are dissolvable, elastically deformable, or retrievable.

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.

摘要： Apparatus for injecting coiled tubing into a bore comprises a rotatable housing (28, 29) having an axis along which coiled tubing is to be translated. A set of rolling elements (12, 14) is rotatably mounted in the housing (28, 29), each rolling element (24) having a skewed axis of rotation with respect to the housing axis and being arranged for rolling contact with an outside diameter of the coiled tubing. The arrangement is such that rotation of the housing (28, 29) relative to the tubing causes the tubing to be moved axially through the rotating housing.
