Abrégé
(EN) An apparatus for metering fluid in a subterranean well includes an electric submersible pump (12) having a motor (16), a seal section (18) and a pump assembly (20) and a metering assembly (34). The metering assembly includes an upper pipe section (36) with an outer diameter (38), the upper pipe section having an upper pressure sensing means, and a lower pipe section (40) with an outer diameter (42) smaller than the outer diameter of the upper pipe section, the lower pipe section having a lower pressure sensing means. A power cable is in electronic communication with the electric submersible pump and with the metering assembly.
(FR) L'invention concerne un appareil permettant de mesurer un fluide dans un puits sous-terrain, lequel comprend une pompe submersible électrique comprenant un moteur, une section joint et un système de pompe et un ensemble de mesure. L'ensemble de mesure comprend une section de tuyau supérieure avec un diamètre externe, la section de tuyau supérieure comprenant un moyen de détection de pression supérieur, et une section de tuyau inférieure avec un diamètre externe inférieur au diamètre externe de la section de tuyau supérieure, la section de tuyau inférieure comprenant un moyen de détection de pression inférieur. Un câble électrique est en communication électronique avec la pompe submersible électrique et avec l'ensemble de mesure.
