A method and apparatus for separating fluids flowing through a downhole well passageway (D) includes separating fluids pumped downhole (WB) by centrifugal separation, gradually increasing centrifugal acceleration, establishing annular flow, gradually establishing annular flow, and receiving fluid in a receiving chamber (2) of increasing cross-sectional area of flow. A method and apparatus is suggested for use of a fluid separator tool (DFS) with tubing for downhole well operations, particulary with coiled tubing (CT).
L'invention concerne un procédé et un appareil permettant de séparer des fluides s'écoulant à travers un passage (D) d'un puits de forage. Ledit procédé consiste à séparer les fluides pompés en fond (WB) par centrifugation, à augmenter progressivement l'accélération centrifuge, à établir un écoulement annulaire, à établir progressivement un écoulement annulaire, et à recueillir le fluide dans une chambre collectrice (2) à section d'écoulement croissante. L'invention concerne également un procédé et un appareil permettant d'utiliser un outil de séparation de fluides (DFS) comprenant des tubes pour des opérations de fond, notamment des tubes spiralés (CT).
