摘要： An apparatus and methods for manipulating and driving casing. The apparatus includes mechanically responsive elements for gripping an interior of a casing joint, and hydraulically responsive elements for gripping an interior of the casing joint responsive to pressure of drilling fluid flowing through the apparatus. One method comprises manipulating a casing joint by mechanically gripping an interior thereof, hydraulically gripping the interior of the casing joint responsive to drilling fluid pressure, and rotating the casing joint. Another method comprises driving casing by applying weight and torque thereto through engagement with an interior thereof.

摘要： A mill is configured to have large debris passages disposed among a series of radially extending blades. The mill center is adapted to accept a retention nut that supports a tool that secures the downhole tool being milled out, such as a packer. Reverse flow takes cuttings into the large open area between the blades to pass up in an annular space around a support for the retention nut. The passage then opens up to a maximum dimension leaving only the tubular wall needed for structural strength to support the mill and conduct cuttings into a debris removal tool.

摘要： The circulation system for a rotary shoe features a fluid diversion to a peripheral zone from which the flow is directed by tubes or housing bores to the vicinity of the cutting structure to improve cooling and removal of debris. Some of the fluid is directed straight through into the mandrel of the tool being milled. If the formation below is at low pressure a packer cup is added to the grip tool attached to the shoe at one end and to the fish at the other end. A swivel is used to prevent the packer cup rotation. Fluid diverted by the packer cup comes up out of the mandrel and into an annular space between the mandrel and the inner wall of the shoe and out from under the shoe by flowing past the cutters. Fluid loss to the formation is minimized and cooling and cutting removal is enhanced.

摘要： A cutting assembly for external conduits on a tubing string features a breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing. Upon severing of the string and applying a pickup force, a tension is applied to each external conduit since the severing of the string happens above all the cutter housings. Each housing cuts at least one conduit and the upper portion of the string brings with it the upper portion of the external conduit while the lower portions of each cut external conduit are retained in the cutter housings that remain downhole below the breakaway. In that manner there are no loose external conduit ends to interfere with and/or disturb subsequent fishing or other wellbore operations.
