摘要： A downhole disconnect tool can include outer housing sections connected to each other with threads, and an inner sleeve received in at least one of the outer housing sections, whereby the inner sleeve limits relative rotation between the outer housing sections in a connect position, and permits relative rotation between the outer housing sections in a disconnect position. A method of disconnecting portions of a tubular string can include connecting a downhole disconnect tool between the tubular string portions, deploying a plug into the tubular string, thereby engaging the plug with an inner sleeve in the downhole disconnect tool, applying a differential pressure across the plug, thereby displacing the inner sleeve relative to outer housing sections of the downhole disconnect tool, and then unthreading the outer housing sections from each other in the well.

摘要： The invention provides a bit breaker comprising a plate that bounds a pipe slot. The bit breaker has two jaws that are at least generally parallel and that respectively define two working surfaces located on opposite sides of the pipe slot. The jaws are each mounted removably to the plate. In some embodiments, the invention is an assembly that further includes a pipe, tool section, tool or pipe joint received in the pipe slot. The pipe, tool section, tool or pipe joint has formed therein two crosswise grooves located on opposite sides of the pipe, tool section, tool or pipe joint. In some embodiments, the plate defines two fixed arms and a fixed base leg, with the two jaws mounted respectively against the two fixed arms. The bit breaker can have an adjustable arm such that the pipe slot can be surrounded about 360 degrees by the bit breaker.

摘要： A method for assembling a down-the-hole drilling apparatus including a drilling device including a casing and a drilling unit arranged during drilling in connection with the casing. The drilling unit includes a drilling head including a drilling arrangement including a first drilling member for drilling a center hole and a second drilling member for reaming the center hole. The drilling members are mutually power transmittingly coupled during drilling to cooperate for rotational, feeding and/or hammering, and removably coupled to enable removal of the first drilling member from a hole. The casing is arranged to be pulled into the hole through a shoulder arranged at an end of the casing. At an opposite end of the drilling arrangement with respect to a drilling surface, is arranged a skirt including a radial internal shoulder for pulling the casing into the hole by cooperation of the internal shoulder and an external shoulder at the end of the casing.

摘要： The invention relates to a method pertaining to a drill support device (290) comprising two relatively movable drill support arms (241; 242), wherein a support space is formed between opposite arm sections (261, 262), in which a drill steel (201) is adapted to be guided and wherein said space is opened and closed by relative displacement of said sections (261, 262). The method includes the step of: —fixing (S401) at least one of said drill support arms (241; 242) by sealingly clamping between, on one side, a support element (670) and, on the other side, a housing section (650), which accommodates a hydraulic cylinder (605) with a hydraulic piston (680), on which hydraulic cylinder (605), said drill support arm (241; 242) is revolvingly mounted, wherein said drill support arm (241; 242) is clamped by means of a screw means (640) by which the housing section (650) is displaceable. The invention also relates to a computer program product comprising program code (P) for a computer (200; 210) for implementing a method according to the invention. The invention also relates to a drill support device (290) and a vehicle (100) equipped with the drill support device (290).

摘要： Feed tools and methods of use for initiating a change in a spindle feed direction from an advance direction that moves the spindle towards a workpiece to a retract direction that moves the spindle away from the workpiece. The tool and methods may use a thrust overload force that is generated on one or more of the components to initiate the shift from forward to retract and/or a lift ring that acts on one or more of the components. The tool and methods may also include a two-stage piston to accomplish the shift. The various components may be used independently or in combination within the tool.
