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 (200) having an expandable section (225), and a polished bore receptacle (25) positioned below the expandable section. The expandable section is run into a wellbore (205), and is positioned to overlap with the bottom portion of a string of casing (210) 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 (260) and at least one slip member (270) on the outer surface. In one aspect, a transition section (275) 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： Embodiments of the present invention relates to hydraulically actuated tools, which may be used to actuate a liner hanger assembly. In one embodiment, the present invention provides a hydraulic setting tool (113) for use in wellbore operations. The setting tool includes a first tubular member (130) and a second tubular member (120) disposed around the outer diameter of the first tubular member. A piston (110) is mechanically attached to an upper portion of the second tubular member and adapted to move axially in relation to the first tubular member. The piston acts to transmit a force to the second tubular member. A slip assembly (162) is operatively connected to the second tubular member and the second tubular member transmits the force to the slip assembly thereby actuating the slip assembly.

摘要： The present invention provides methods and apparatus for reducing friction and preventing galling between surfaces in a wellbore. In one aspect of the invention, mating threads are coated with fullerene to reduce galling of the threads during make up and break down. In another aspect, a fullerene is used between surfaces of an expansion tool and a tubular to be expanded in order to reduce friction and prevent galling therebetween. Preferably, the fullerene is a spherically shaped carbon 60 molecule otherwise known as buckyball or C 60 . The fullerene coating provides an intermediate surface between two metal surfaces, thereby preventing galling between the two surfaces. In another aspect of the invention, the fullerene is placed between the roller of an expander tool and the surface of the tubular to be expanded in order to reduce friction and galling.

摘要： The present invention provides an apparatus and method for expanding a first tubular (120) against a second tubular (110). In one aspect, an expander tool (300) includes a mandrel coupled to a spline assembly (330, 430) such that an annular space is formed between the same. Seals are placed between the mandrel and the spline assembly to retain a fluid in the annular space. In operation, the mandrel (310) is rotated, which, in turn, rotates the expander members (350). Rotation of the mandrel also causes the spline assembly (430, 330) to extend axially, thereby pulling a first seal (360) closer to a second seal (355). As a result, the pressure in the annular space (340) rises due to the compression of the fluid in the annular space. The rise in pressure extends the expander members into contact with the first tubular and expands the first tubular against the second tubular.
摘要翻译：本发明提供一种用于使第一管（120）相对于第二管（110）膨胀的装置和方法。在一个方面，扩展器工具（300）包括联接到花键组件（330,430）的心轴，使得在其之间形成环形空间。将密封件放置在心轴和花键组件之间以将流体保持在环形空间中。在操作中，心轴（310）旋转，其又使膨胀器构件（350）旋转。心轴的旋转还使得花键组件（430,330）轴向延伸，从而拉动更靠近第二密封件（355）的第一密封件（360）。结果，环形空间（340）中的压力由于环形空间中的流体的压缩而升高。压力的升高使膨胀器构件与第一管状体接触，并使第一管状体相对于第二管状物膨胀。
