摘要： A threaded connection for a conduit is disclosed. The connection includes a male member having threads on it defining a load flank lead, a stab flank lead and a nominal lead. A female member has threads thereon adapted to mate with the threads on the male member. The threads on the female member define a load flank lead, a stab flank lead a nominal lead. At least one of the load flank lead and the stab flank lead, on at least one of the female member and the male member, is changed at a predetermined rate beginning at a selected distance from an end of the threads. The load lead and the stab lead are different from each other over at least part of the thread length.

摘要： A bonnet assembly for a blowout preventer uses a seal carrier that is removable so as to allow for efficient and easy seal replacement. The seal carrier has: a recess adapted to at least partially embed a seal for sealing the bonnet assembly to a body of the blowout preventer; and a first connecting rod coupled to and extending from an inner surface of the seal carrier, where the first connecting rod has a fastening structure proximal to a distal end of the first connecting rod, where the fastening structure is adapted to engage with a first fastening device, and where the seal carrier is removable from the bonnet assembly when the first fastening device is disengaged from the fastening structure.

摘要： A threaded connection including a pin member and a box member, and methods for manufacturing and forming said threaded connection. The pin member has a pin thread with a pin thread crest, a pin thread root, a pin load flank, and a pin stab flank. The box member has a box thread with a box thread crest, a box thread root, a box load flank, and a box stab flank. At least one of the pin thread crest, the pin load flank, the pin stab flank, the box thread crest, the box load flank, and the box stab flank has at least one perturbation formed thereon. Upon a selected make-up of the pin member with the box member, an increased contact stress exists between the pin thread and the box thread at the at least one perturbation.

摘要： There is disclosed an actuator for delivering a supplementary force to the piston of a shear ram in a blowout preventer (BOP), and a corresponding BOP. In one embodiment, a supplementary force actuator (12) is disclosed for use on a hydraulic ram (10), the actuator comprising an actuator body (30) connected to the hydraulic ram; first and second chambers (38, 36) located in the body, the chambers isolated from each other by an actuator piston (46); a rod (42) connected to an operating piston (24) of the hydraulic ram, passing through the first chamber and the actuator piston, and extending into at least a portion of the second chamber; wherein the actuator piston is releasably enga.geable to the rod by gripping means (48); and wherein the hydraulic ram is operated by a force from movement of the operating piston and by a supplementary force from movement of the actuator piston.

摘要： A threaded pipe connection includes a box member (130) generally dovetail-shaped threads (131, 132), each with stab flanks (136, 134), load flanks (133, 135), roots (137, 139), and crests (138, 140). The pin member (30) also has multiple external, generally dovetail-shaped threads (31, 32), each with stab flanks (34, 36), load flanks (33, 35), roots (37, 39), and crests (38, 40). The internal threads (131, 132) of the box member (130) each increase in width in one direction, while the external threads (31, 32) of the pin member (30) increase in width in the other direction so that the complementary flanks of the respective threads move into engagement upon make-up of the connection.

摘要： A system (10) for drilling a subsea well (30) from a rig (20) through a subsea wellhead below the rig (20) includes a wellhead stack (37) which is mounted on the subsea wellhead. The wellhead stack (37) comprises at least a subsea blowout preventer stack and a subsea diverter (106, 108). A drill string extends from the rig (20) through the wellhead stack (37) into the well (30) to conduct drilling fluid from the rig (20) to a drill bit in the well (30). A riser (52) which has one end coupled to the wellhead stack (37) and another end coupled to the rig (20) internally receives the drill string such that a riser annulus is defined between the drill string and the riser (52). A well annulus (66) extends from the bottom of the well (30) to the subsea diverter (106, 108) to conduct fluid away from the drill bit. A pump has a suction side in communication with the well annulus (66) and a discharge side in communication with the rig (20) and is operable to maintain a selected pressure gradient in the well annulus (66).
