摘要： A shear coupling can be used with reciprocating and rotary pumps. The shear coupling uses a shear nut and connecting member as the shear element. The connecting member and shear nut are located inside the axial bore of the shear coupling to protect from corrosive wellbore elements. The coupling members may be connected by matching polygonal shaft and hub profiles on the coupling members to transmit torque. The shaft and hub may have octagonal profiles for better torque transmission capacity. The shear nut may be isolated from large alternating stresses due to pretensioning of the connecting member. The length of the connecting member, especially when pretensioned, and a reduced cross-section that may be formed on the outer surface of the shear coupling increase the overall flexibility of the shear coupling, thereby increasing the resistance to bending stress.

摘要： A horizontal drilling machine with an in-situ detection device, including a support frame, an armored cable, a steel pipe-straightening mechanism, a steel pipe-feeding mechanism, a motor, a power head, a drill pipe, a rotating chuck, a damper, a non-core drilling tool, the in-situ detection device, a fishing device and a thrust cylinder. The steel pipe-straightening mechanism, the steel pipe-feeding mechanism, the rotating chuck and the damper are sequentially fixed on the support frame from left to right. One end of the thrust cylinder is hinged with the support frame, and the other end is connected to the power head. The active drill pipe of the power head is connected to the drill pipe. An end of the armored cable is connected to the fishing device in the drill pipe, and the fishing head of the fishing device is connected to the spearhead of the non-core drilling tool.

摘要： A method for joining metallic well tubulars to be lowered into a wellbore (4) comprises the steps of: a) providing a first well tubular (6) having an upper end surface (6a), and a second well tubular (7) having a lower end surface (7a); b) lowering the first well tubular (6) into the wellbore (4), leaving the upper end thereof outside the wellbore (4); c) setting the second well tubular (7) in an axially aligned position on the first well tubular (6), with the lower end surface (7a) of the second well tubular (7) set against the upper end surface (6a) of the first well tubular (6); d) keeping the first and second well tubulars (6, 7) in said axially aligned position; e) welding the upper end of the first well tubular (6) to the lower end of the second well tubular (7), forming a circumferential weld bead (WL) in a position corresponding to said upper and lower end surfaces (6a, 7a); and f) lowering into the wellbore (4) the first well tubular (6) and the second well tubular (7) welded together. Step e) comprises the operations of: providing at least one laser welding head (13), configured for directing a laser beam (LB) towards a circumferential working zone (WA) that includes an upper end portion of the first well tubular (6) and a lower end portion of the second well tubular (7), the at least one laser welding head (13) being displaceable around the circumferential working zone (WA) according to a respective trajectory of revolution; providing at least one induction-heating device (141, 142), which is displaceable substantially according to the trajectory of revolution of the at least one laser welding head (13), the at least one induction-heating device (141, 142) being set upstream, respectively downstream, of the at least one laser welding head (13), with reference to the direction of revolution (R) of the at least one laser welding head (13); causing revolution of the at least one laser welding head (13) and revolution of the at least one induction-heating device (141, 142), in such a way that: the laser beam (LB) progressively forms the circumferential weld bead (WL); and the at least one induction-heating device (141, 142) supplies heat to a corresponding part (PH1, PH2) of the circumferential working zone (WA), which comprises respective parts of said upper and lower end portions of the respective first and second well tubulars (6, 7), before the laser beam (LB) reaches said corresponding part (PH, PH2), respectively after the laser beam (LB) has reached said corresponding part (PH1, PH2).

摘要： An automated pipe tripping apparatus includes an outer frame and an inner frame. The inner frame includes a tripping slips and iron roughneck. The automated pipe tripping apparatus may, in concert with an elevator and drawworks, trip in a tubular string in a continuous motion. The tripping slips and iron roughneck, along with the inner frame, may travel vertically within the outer frame. The weight of the tubular string is transferred between the tripping slips and the elevator. The iron roughneck may make up or break out threaded connections between tubular segments, the upper tubular segment supported by the elevator and the lower by the tripping slips. An automated pipe handling apparatus may remove or supply sections of pipe from or to the elevator. A control system may control both the automated pipe tripping apparatus and the elevator and drawworks.
