    摘要： A system for coupling a pipe segment to a pipe string is provided that includes a top drive assembly having an output shaft; and a pipe running tool coupled to the top drive assembly and rotatable by the output shaft of the top drive assembly. The pipe running tool includes an internal gripper for insertion within an internal diameter of the pipe segment and a tapered slip cone section, which slidably receives corresponding tapered surfaces of a plurality of slips, such that a vertical force on the slips causes the slips to move radially outwardly into gripping engagement with the internal diameter of the pipe segment, and wherein the vertical force applied to the slips is sufficient to allow the gripping engagement of the slips with the internal diameter of the pipe segment to transmit a torque from the top drive output shaft to the pipe segment.

    摘要： A rotary seal assembly for a rotary support table for use in drilling systems and the like to provide pressurized fluid to a rotary slip assembly disposed within the rotary support table is provided. The rotary seal assembly is designed to be coupled to an existing rotary support table which is used to rotate a drill string, and includes a powered slip that is powered into an engaged position to securely engage a pipe segment, for example, a casing segment. The rotary seal assembly generally comprises a ribbon of expandable material having an outer surface in fluid communication with a source of pressurized fluid, and an inner surface cooperative with a rotary housing, the rotary seal having a plurality of openings capable of communicating fluid between said outer and inner surfaces, wherein the outer seal surface has a surface area greater than the inner surface such that when the pressurized fluid is conducted to the outer surface of the seal a differential pressure between the outer and inner surfaces is created such that the inner surface of the seal is expanded to engage the rotary housing and form an annular fluid duct providing fluid communication between the pressurized fluid source and the rotary housing. A method of operating a rotary table and powered slip assembly utilizing the rotary slip assembly of the current invention is also provided.

    摘要： A clamping device for supporting a well string in a borehole includes a base plate with a central opening and primary clamp body clamp body supported for linear motion relative to the base plate. The clamping device further includes other clamp bodies supported for independent linear motion relative to the base plate. In certain embodiments, the clamping bodies are supported for pivoting motion to open and close the central opening. Each of the clamp bodies carries a gripping member on a face thereof for engaging a well string component received in the central opening. A drive mechanism is coupled to the clamp bodies and configured to move the clamp bodies relative to the base plate.
