Title
(EN) LOGGING PERFORATION FLOW IN A WELLBORE
(FR) DIAGRAPHIE DE FLUX DANS DES PERFORATIONS D'UN PUITS DE FORAGE
Abstract
(EN)
A measurement apparatus for non-invasively logging the flow of perforations in a well casing lining a wellbore. The measurement apparatus includes a plurality of transducers arranged adjacent an outer surface of the measurement apparatus and at predefined azimuthal angular positions with respect to a longitudinal axis of the measurement apparatus, where the transducers are adapted to transmit and detect an acoustic pulse, and where each transducer is arranged at a different azimuthal angle with respect to each of the remaining transducers.
(FR)
L'invention concerne un appareil de mesure pour la diagraphie non invasive du flux dans des perforations d'un tubage de puits chemisant un puits de forage. L'appareil de mesure comprend une pluralité de transducteurs disposés de manière adjacente à une surface externe de l'appareil de mesure et à des positions angulaires azimutales prédéfinies par rapport à un axe longitudinal de l'appareil de mesure, les transducteurs étant conçus pour transmettre et détecter une impulsion acoustique et chaque transducteur étant disposé à un angle azimutal différent par rapport à chacun des transducteurs restants.
