Title (EN) MULTIPHASE FLOW MEASUREMENT SYSTEM
(FR) SYSTEME DE MESURE D"ECOULEMENT POLYPHASIQUE
Abstract:
(EN) An automatic well test system (100) utilizes a two phase vortex separator 104 connected to a pair of Coriolis flowmeters (154, 166) to measure volumetric flow rates in three phase flow. Measurements are performed according to a process (P200) including an iterative convergence technique. Measurements are enhanced by the use of real time density and water cut measurements from a water cut meter (172) and a water density meter.
(FR) L"invention concerne un système (100) automatique d"essai de puits, qui utilise un séparateur (104) tourbillonnaire en deux phases relié à deux débitmètres (154, 166) de Coriolis pour mesurer les débits volumétriques dans un écoulement à trois phases. Des mesures sont effectuées selon un procédé (P200) comprenant une technique de convergence itérative. Les mesures sont améliorées grâce à des mesures en temps réel de la densité de l"eau et de la teneur en eau provenant d"un moyen de mesure (172) de teneur en eau et d"un moyen de mesure de densité de l"eau.
