摘要： An annular blowout preventer packer unit having an annulus of elastomeric material in which is embedded metallic drive inserts provided in an outward circle about the axis. Metallic lead inserts (L) are provided in an inward circle about the axis. The top (42) and bottom plates (51) of the drive inserts (D) have two angled longitudinal forward surfaces which interface with reverse angled adjacent longitudinal rearward surfaces of the top (44) and bottom plates (53) of the lead inserts, respectively. When the BOP piston is closed, the drive inserts cause the lead inserts to advance inwardly a greater radial distance than the advance of the drive inserts. The result is that less stroke may be required to close the blowout preventer, and a controlled, predictable, uniform movement of the lead inserts is achieved. The drive inserts top plates are broad across their rearward longitudinal surface operably covering the area behind the lead inserts on closure of the packer unit. The shape of the drive inserts allows the lead inserts to be driven to a smaller diameter without opening up the back side and causing outer diameter elastomer loss to the unit.

摘要： A positive-displacement pump includes multiple pumping elements, each pumping element having a pressure vessel with a first and a second chamber and a separating member disposed between the first and second chambers. The first chambers and the second chambers are hydraulically connected to receive and discharge fluid, wherein the separating members move within the pressure vessels in response to pressure differential between the first and second chambers. A valve assembly having suction and discharge valves communicates with the first chambers. The suction and discharge valves are operable to permit fluid to alternately flow into and out of the first chambers. A hydraulic drive alternately supplies hydraulic fluid to and withdraws hydraulic fluid from the second chambers such that the fluid discharged from the first chambers is free of pulsation.

摘要： Une unité de garniture annulaire d'étanchéité pour un obturateur comprend un anneau torique en matériau élastomère dans lequel sont incorporées des insertions métalliques de commande agencées en un cercle extérieur autour de l'axe. Des insertions métalliques d'attaque (L) sont agencées en un cercle intérieur autour de l'axe. Les plaques supérieure (42) et inférieure (51) des insertions de commande (D) ont deux surfaces antérieures longitudinales adjacentes qui forment un angle inverse sur les plaques supérieure (44) et inférieure (53) des insertions d'attaque, respectivement. Lorsque le piston de l'obturateur est fermé, les insertions de commande font avancer les insertions d'attaque vers l'intérieur, sur une distance radiale plus grande que celle couverte par les insertions de commande. Par conséquent, une course plus courte est requise pour fermer l'obturateur, et on obtient un déplacement contrôlé, prévisible et uniforme des insertions d'attaque. La surface postérieure longitudinale des plaques supérieures des insertions de commande sont larges et recouvrent pendant leur fonctionnement la zone située derrière les insertions d'attaque lorsque la garniture d'étanchéité est fermée. La forme des insertions de commande permet d'entraîner les insertions d'attaque jusqu'à un plus petit diamètre sans ouvrir le côté postérieur et provoquer des pertes de l'élastomère formant le diamètre extérieur de l'unité.

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).

摘要： A rotating diverter (108) for isolating fluid in a well (30) from other fluid above the well (30) is provided. The rotating diverter (108) includes a housing body (162) which has a bore (168) running through it. A retrievable spindle assembly (178) which includes a spindle (178) and a bearing assembly (184) is disposed in the bore (168). The bearing assembly (184) supports the spindle (178) for rotation. The spindle (178) is adapted to receive and seal around a tubular member, and rotation of the tubular member rotates the spindle (178) within the bore (168). A lock member (176) is disposed in the housing body (162) to secure the retrievable spindle assembly (178) to the housing body (162).

摘要： A positive-displacement pump (102) includes multiple pumping elements (355, 356). Each pumping element having a pressure vessel (356) with a first (372) and a second (370) chamber and a separating member (362) disposed between the first (372) and second (370) chambers. The first (372) chambers and the second (370) chambers are hydraulically connected to receive and discharge fluid, wherein the separating members (362) move within the pressure vessels (356) in response to pressure differential between the first (372) and second (370) chambers. A valve assembly (378) having suction (380) and discharge (382) valves communicates with the first (372) chambers. The suction (380) and discharge (382) valves are operable to permit fluid to alternately flow into and out of the first (372) chambers. A hydraulic drive (420) alternately supplies hydraulic fluid to and withdraws hydraulic fluid from the second (370) chambers such that the fluid discharged from the first (372) chambers is free of pulsation.
