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.

摘要： A method of anchoring tubing in a bore comprising: providing tubing having a section with outer surface portions defining a tubing profile, and configured to describe an outer diameter less than a first diameter. The tubing is located within a bore having an internal diameter equal to the first diameter and defining a bore profile. The tubing is then reconfigured such that the tubing profile engages with the bore profile, anchoring the tubing within the bore.

摘要： An apparatus and a method for expanding a downhole tubular. The apparatus includes a mandrel defining at least one curved support surface. The apparatus further includes an expansion member defining a curved bearing surface for contact with the support surface and corresponding to the mandrel support surface. The expansion member is movable relative to the mandrel, whereby the surfaces are in contact and movable over one another to move the expansion member from a smaller diameter first configuration towards a larger diameter second configuration.

摘要： A method of anchoring tubing in a bore comprises: providing first tubing having a section with a wall configured to provide outer surface portions describing a diameter less than a first diameter. The tubing is located within a bore comprising a first section having an internal diameter greater than the first diameter and a second section having an internal diameter corresponding to the first diameter, with the tubing section in the first section of the bore. The tubing section is then reconfigured such that the outer surface portions describe a tubing diameter greater than the first diameter. The tubing is then axially translated relative to the bore to locate the tubing section in the second section of the bore such that the outer surface portions are restrained to the first diameter by the bore, and the outer surface portions engage with the bore.

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： The present invention provides an apparatus and method expanding a portion of a tubular. The expansion apparatus is run into a wellbore on a working string. The expansion apparatus first comprises a rotary expander for expanding an expandable tubular. The expansion apparatus further comprises a spline assembly for coupling the rotary expander to a motor disposed on the work string. The rotary expander and spline assembly have hollow bodies that allow them to encircle the work string and rotate relative thereto. The spline assembly comprises an inner sleeve and outer sleeve. The inner sleeve is attached to the motor and the outer sleeve is attached to the rotary expander. The inner and outer sleeves are coupled to each other using a spline and groove connection. The connection allows the rotary expander to be rotated by the motor, while at the same time, allow the rotary expander to move axially relative to the motor. The rotary expander comprises two rows of rollers for expansion against the tubular. The position of the rollers on the first row is skewed in one direction relative to the longitudinal axis. The rollers on the second row are skewed in an opposite direction. When actuated, the skew angle of the rollers will cause the expander tool to move axially. Because the rollers of the two rows are placed at opposing skew angles, alternating actuation between the two rows of rollers causes the expander to move in opposite axial directions during expansion.
