Title
(EN) BLOWOUT PREVENTER ASSEMBLY
(FR) ENSEMBLE BLOC OBTURATEUR DE PUITS
Abstract
(EN)
A blowout preventer assembly comprising a blowout preventer and control apparatus, the blowout preventer comprising a housing a sealing element and a fluid pressure operated actuator mounted in the housing, the actuator 18 dividing the interior of the housing into two chambers, namely an open chamber and a close chamber, substantially preventing flow of fluid between the two chambers, and being movable, by means of the supply of pressurised fluid to the close chamber, to urge the sealing element into sealing engagement with a drill pipe extending through the blow out preventer, the control apparatus including a close line which extends from the exterior of the housing to the close chamber, and a source of pressurised fluid which is connected to the close line, wherein the source of pressurised fluid is located adjacent to the housing.
(FR)
L'invention concerne un ensemble bloc obturateur de puits qui comprend un bloc obturateur de puits et un appareil de commande, le bloc obturateur de puits comprenant un boîtier, un élément d'étanchéité et un actionneur sensible à la pression de fluide monté dans le boîtier, l'actionneur 18 divisant l'intérieur du boîtier en deux chambres, à savoir une chambre ouverte et une chambre fermée, empêchant sensiblement un écoulement de fluide entre les deux chambres, et étant mobile, au moyen de l'alimentation en fluide sous pression vers la chambre fermée, pour pousser l'élément d'étanchéité en prise d'étanchéité avec un tuyau de forage s'étendant à travers le bloc obturateur de puits, l'appareil de commande comprenant une conduite fermée qui s'étend à partir de l'extérieur du boîtier vers la chambre fermée, et une source de fluide sous pression qui est reliée à la conduite fermée, la source de fluide sous pression étant disposée au voisinage du boîtier.
