A fluid recovery system (10) for collecting formation fluid at the surface of a well (12) includes a downhole jet pump (20) and a surface diaphragm pump (40) having a plurality of diaphragms (42). The jet pump includes a fluid nozzle (22), an intake (24) directing the formation fluid into a jet (26), a mixing tube (28) for mixing the power fluid and the formation fluid, and a diffuser (30) for converting the velocity of the mixed fluid to pressure. A flow meter (50) and a pressure sensor (52) monitor the quantity and pressure of the power fluid to the jet pump.

L'invention concerne un système de récupération de fluide (10) destiné à collecter un fluide de formation à la surface d'un puits (12) comprenant une pompe à jet de fond (20) et une pompe à diaphragme de surface (40) équipée de plusieurs diaphragmes (42). La pompe à jet comprend une buse de fluide (22), une entrée (24) dirigeant le fluide de formation dans un jet (26), un tube de mélange (28) destiné à mélanger le fluide de puissance et le fluide de formation, et un diffuseur (30) destiné à convertir la vitesse du fluide mélangé à la pression. Un débitmètre (50) et un capteur de pression (52) commandent la quantité et la pression de fluide de puissance dans la pompe à jet.
