摘要： A downhole tool for connection in a work string to prevent premature activation of weight set tools on the work string. The tool has moveable pads which contact the tubing wall and thereby support the weight of the work string. The pads are activated by increasing fluid pressure in the annulus between the tool and tubing wall and deactivated by increasing fluid pressure through the central bore of the tool.

摘要： An apparatus for expanding a portion of a tubular within a wellbore. The expansion assembly first comprises an expander tool. The expander tool is preferably a rotary expander tool which is lowered into the wellbore at the lower end of a working string. In one aspect, the rotary expander tool defines a tubular body having recesses, with each recess containing a compliant roller. The expansion assembly further comprises a chamber having a resistive medium therein. In one arrangement, the medium is a clean oil loaded into the chamber before being run into the wellbore. The fluid chamber is sized and configured to sealingly receive an elongated lower portion of the body of the expander tool. As the body of the expander tool travels into the fluid chamber, it encounters resistance from the fluid loaded therein. The fluid serves as a resistant force to the downward movement of the drill string and the expander tool during the expansion process, thereby preventing any rapid springing of the pipe string above it.

摘要： A mono-diameter wellbore casing. A tubular liner and an expansion cone are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with a pre-existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the expansion cone and into the annular region between the tubular liner and the new section of the wellbore. The inner and outer regions of the tubular liner are then fluidicly isolated. A non hardenable fluidic material is then injected into a portion of an interior region of the tubular liner to pressurize the portion of the interior region of the tubular liner below the expansion cone. The tubular liner is then extruded off of the expansion cone. The overlapping portion of the pre-existing casing and the tubular liner are then radially expanded using an expansion cone.

摘要： A method of repairing tubulars downhole is described. A swage is secured to a force magnification tool, which is, in turn, supported by an anchor tool. Applied pressure sets the anchor when the swage is properly positioned. The force magnification tool strokes the swage through the collapsed section. The anchor can be released and weight set down on the swage to permit multiple stroking to get through the collapsed area. The swage diameter can be varied.

摘要： The present invention provides an expandable tubular having improved polished bore receptacle protection. The present invention further provides methods for completing a wellbore through the use of an expandable string of casing having improved polished bore receptacle protection. In one aspect, the invention includes a liner member having an expandable section, and a polished bore receptacle positioned below the expandable section. The expandable section is run into a wellbore, and is positioned to overlap with the bottom portion of a string of casing already set within the wellbore. The expandable section is then expanded into frictional engagement with the surrounding casing. The expandable section optionally includes at least one sealing member and at least one slip member on the outer surface. In one aspect, a transition section is provided between the expandable section and the polished bore receptacle. The transition section defines a sloped inner diameter which provides further protection for the sealing surfaces of the polished bore receptacle as tools, fluid, and tubulars are transited downhole through the polished bore receptacle.

摘要： An apparatus and method of creating a seal between two coaxial tubulars so as to create a hanger and a packer. A first tubular is disposed coaxially within a portion of a second, larger tubular. A portion of the first tubular is expanded into frictional contact with the second tubular, thereby creating a liner and a hanger. In one embodiment, a pattern of grooves and profile cuts are formed in the surface of a portion of the first tubular body. The grooves in one aspect define a continuous pattern about the circumference of the tubular body which intersect to form a plurality of substantially identical shapes, such as diamonds. The grooves and profile cuts serve to improve the tensile strength of the tubular body. At the same time, the grooves and profile cuts allow for expansion of the tubular body by use of less radial force. The grooves and profile cuts further provide a gripping means, providing additional frictional support for hanging the expanded tubular onto the inner surface of a surrounding second tubular.

摘要： A method and apparatus for creating a seal between two coaxial strings of pipe. The method and apparatus have utility in one embodiment for sealing the annulus between the tubing and the casing within a hydrocarbon wellbore. According to the method of the present invention, an expander tool is positioned at a selected depth within the tubing, and then actuated in order to expand the tubing against the inner wall of the casing wall. The expander tool is rotated in order to provide a fluid seal in the annulus. In this way, the tubing string becomes its own packer. In the preferred embodiment, an elastomeric seal is provided around the outer surface of the tubing to enhance the fluid seal. Further, a slip ring is provided around the outer surface of the tubing to provide a gripping means between the tubing and the casing. In the preferred embodiment, rollers of the expander tool are aligned with the seal ring and slip ring before expansion.
