Abstract

Fremgangsmåte og system for under-søkelse av en fluid-strøm, for eksempel i en olje- eller gass-brønn, omfattende utsendelse av et akustisk signal, for-trinnsvis med frekvens i ultralyd-området, langs en valgt akse fra en akustisk kilde ved en første posisjon.Spredte akustiske signaler mottas ved hjelp av minst én første mottaker plassert med en avstand fra det utsendte signalets akse, for derved å måle eller detektere akustiske signaler som er spredt eller reflektert sideveis i fluid-strømmen.A method and system for examining a fluid flow, for example in an oil or gas well, comprising transmitting an acoustic signal, preferably with frequency in the ultrasonic range, along a selected axis from an acoustic source at Scattered acoustic signals are received by means of at least one first receiver located at a distance from the axis of the transmitted signal, thereby measuring or detecting acoustic signals which are scattered or reflected laterally in the fluid flow.
