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 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.

摘要： A tubular connection (10, 12) is shown having wedge threads (24, 26), the individual threads preferably interlocking by having wider crest dimensions than respective root dimensions, but with the stab flanks (30) and load flanks (32) generally angling in the same direction with respect to the longitudinal axis of the connection. Thus, when the stab flank is positive, it is less positive than the load flank is negative. Conversely, when the stab flank is negative, it is more negative than the load flank is positive. Preferably, the roots and crests radially interfere prior to full makeup. The connection achieves distribution over the entire thread length of the bearing stresses that resist torsional makeup, of the torque load, and of sealing. The slant of the flanks achieves self-centering of the pin member with respect to the box member either during assembly or disassembly depending on the angling in the respective embodiments.

摘要： The same size and weight of tubular products, but in different grades of material, are made for universal connection but with seal areas that differ appropriately for adequate sealing without overstressing the connection members for the pressures encountered where each tubular length is put in service. The angle of the conically tapered seal on all box members (7) is made the same for all grades of the products. The pin member (10) of medium grade is made with an equal length seal area (16) and adjacent contacting area (11) on its forward end. The pin member (10) of higher grade is made with a longer length seal area than its adjacent contacting area. The pin member of lower grade is made with a shorter length seal area than its adjacent contacting area, thereby also placing the seal area further from the pin member distal end. This effectively forms a nose extension on the pin member (10) which stiffens the pin member (10) of lower grade and enhances the conical seal area forward of the first thread, which seal is spaced at a distance from the distal end by a non-sealing nose extension that is at least as long as the sealing area. The integrity of the seal is improved, the bearing surface is enlarged and the tendency of galling is reduced.

摘要： On fabrique des produits tubulaires de mêmes taille et poids mais dans différentes qualités de matériau, pour un raccordement universel, avec des surfaces d'étanchéité différant de manière appropriée, afin de permettre une étanchéité adéquate sans soumettre à un effort excessif les éléments de raccordement, pour les pressions rencontrées là où chaque élément de raccordement est mis en service. L'angle du joint conique sur tous les éléments femelle (7) est le même pour toutes les qualités des produits. L'élément mâle (10) de qualité moyenne a une surface d'étanchéité (16) et une surface de contact adjacente (14) d'égale longueur. L'élément mâle (10) de qualité supérieure a une surface d'étanchéité plus longue par rapport à sa surface de contact adjacente. L'élément mâle de qualité inférieure a une surface d'étanchéité de longueur plus courte par rapport à sa surface de contact adjacente, ce qui place également la surface d'étanchéité plus loin à partir de l'extrémité distale de l'élément mâle. Cela a pour effet de former une prolongation en forme de nez sur l'élément mâle (10), rigidifiant l'élément mâle de qualité inférieure et augmentant la surface du joint d'étanchéité conique en avant du premier filetage. Ledit joint d'étanchéité est espacé à une certaine distance de l'extrémité distale par un prolongement en forme de nez non étanche, qui est au moins aussi long que la surface d'étanchéité. Ainsi on améliore l'intégralité du joint d'étanchéité, on élargit la surface de support et on réduit la tendance au grippage.
