    摘要: A flow control device comprises a fluid pathway configured to provide fluid communication between an exterior of a wellbore tubular and an interior of the wellbore tubular, a flow restriction disposed in a fluid pathway, a flow blockage disposed in the fluid pathway, and a retaining member configured to maintain the flow blockage within the fluid pathway and allow access to the flow blockage within the fluid pathway. The flow blockage substantially prevents a fluid flow through the fluid pathway.

    摘要: The present invention provides a method for producing hydrocarbon gas from a wellbore and a control valve assembly for said wellbore. The wellbore comprises a wellhead, a production zone, a production tubing, and a velocity string installed inside the production tubing. The method comprises allowing gas to flow from the production zone through the velocity string, said gas forming a primary gas stream, and controlling the flow of gas from the annulus between the outer wall of the velocity string and the inner wall of the production tubing to the primary gas stream by means of the control valve wherein a controlled mass flow of said gas is combined with the primary gas stream.

    摘要: Apparatuses and methods to communicate with a zone below a subsurface safety valve (104, 204, 404) independent of the position of a closure member (106) of the safety valve are disclosed. The apparatuses and methods include deploying a subsurface safety valve (104, 204, 404) to a profile located within a string of production tubing. The subsurface safety valve (104, 204, 404) is in communication with a surface station through an injection conduit (150,152; 250,252; 450;452) and includes a bypass pathway (144, 244, 444) to inject various fluids to a zone below. A redundant control to actuate subsurface safety valve (104, 204, 404) can include a three-way valve (180, 280) or three-way manifold 480 connecting the injection conduit (150,152; 250,252; 452) or the hydraulic ports (140,142; 240,242; 442') to the subsurface safety valve (104, 204, 404).

    摘要: L'invention concerne une vanne de sécurité pour puits pétroliers et des outils de mise en place ou de retrait de ladite vanne. Cette vanne comprend de façon classique un organe mobile d'obturation (11) un coulisseau tubulaire interne (9) un ressort de rappel (10) du coulisseau vers sa position haute des moyens de déplacement hydraulique du coulisseau vers le bas par pressurisation d'un fluide de commande, un système d'ancrage (14) de la vanne dans un manchon-réceptacle (1) et des garnitures d'étanchéité (15, 16) au contact dudit manchon-réceptacle (1). La vanne conforme à l'invention se caractérise en ce que le système d'ancrage est un système mécanique à sollicitation hydraulique, comprenant un piston-baladeur tubulaire (58) soumis à la pression du fluide de commande en vue d'être déplacé vers le haut par ce fluide, et une douille de verrouillage (55) située au-dessus du piston-baladeur en vue d'être repoussée vers le haut par ce dernier : au cours de son déplacement cette douille manoeuvre et verrouille des chiens d'ancrage (54) prévus flottants dans le corps du verrou.
