Title
(EN) DEVICE FOR CONTROLLING A PASSAGE OF FLUID IN A TUBING STRING AND METHOD OF OPERATING IT
(FR) DISPOSITIF DE COMMANDE D'UN PASSAGE DE FLUIDE DANS UNE COLONNE DE PRODUCTION ET SON PROCÉDÉ DE FONCTIONNEMENT
Abstract
(EN)
The present application discloses a device for controlling a passage of fluid in a tubing string. The device comprises a fluid chamber and two pistons for interact-ing with a fluid inside the fluid chamber. Each piston is adapted for catching an object received through the tubing string from an uphole side of the device. Also, at least one of the pistons is adapted for controlling the passage of fluid, and the pistons and the fluid chamber are arranged so that the pistons are directed in the same direction along the tubing string.
(FR)
La présente invention concerne un dispositif de commande d'un passage de fluide dans une colonne de production. Le dispositif comprend une chambre de fluide et deux pistons pour interagir avec un fluide à l'intérieur de la chambre de fluide. Chaque piston est conçu pour capturer un objet reçu par la colonne de production à partir d'un côté tête de puits du dispositif. De plus, au moins l'un des pistons est conçu pour commander le passage de fluide, et les pistons et la chambre de fluide sont agencés de telle sorte que les pistons sont dirigés dans la même direction le long de la colonne de production.
