Title (EN) THREE-PHASE FLOW IDENTIFICATION AND RATE DETECTION USING ACOUSTIC GUIDE ARRAY
(FR) IDENTIFICATION D'ÉCOULEMENT À TROIS PHASES ET DÉTECTION DE DÉBIT AU MOYEN D'UN RÉSEAU DE GUIDAGE ACOUSTIQUE
Abstract:
(EN) An apparatus for estimating a fraction of each component of a fluid of interest flowing in a cased borehole and a property of the fluid includes an acoustic waveguide sensor having a waveguide configured to guide an acoustic signal along a waveguide path and an array of acoustic transducers coupled to the waveguide for transmitting and receiving an acoustic signal, the acoustic waveguide sensor being configured to transmit and receive a compression-wave acoustic signal that is reflected off of the casing and transmit and receive a shear-wave acoustic signal that propagates along the path. A controller is coupled to the waveguide sensor and configured to perform a compression-wave acoustic measurement on the fluid using the acoustic waveguide sensor in order to estimate the fraction of each component of the fluid and to perform a shear-wave acoustic measurement in order to estimate the property of the fluid.
(FR) L'invention concerne un appareil d'estimation d'une fraction de chaque composant d'un fluide d'intérêt s'écoulant dans un trou de forage tubé et d'une propriété du fluide ; l'appareil comprend un capteur de guide d'onde acoustique possédant un guide d'onde conçu pour guider un signal acoustique le long d'un chemin de guide d'onde et un réseau de transducteurs acoustiques couplés au guide d'onde pour transmettre et recevoir un signal acoustique, le capteur de guide d'onde acoustique étant conçu pour transmettre et recevoir un signal acoustique d'onde de compression qui est réfléchi par le tubage et transmettre et recevoir un signal acoustique d'onde de cisaillement qui se propage le long du chemin. Un dispositif de commande est couplé au capteur de guide d'onde et conçu pour exécuter une mesure acoustique d'onde de compression sur le fluide en utilisant le capteur de guide d'onde acoustique afin d'estimer la fraction de chaque composant du fluide et d'exécuter une mesure acoustique d'onde de cisaillement afin d'estimer la propriété du fluide.
