ULTRASONIC-IMAGING AND VELOCIMETRY IN 2-PHASE PIPE-FLOW

This paper presents the first results of an experimental and theoretic al investigation of the feasibility of using ultrasonic measurements i n multiphase pipe flow. Extant downhole flow rate measurement technolo gy used in the petroleum industry is not adequate in some multiphase f low regimes, particularly when the well is deviated from vertical. Ult rasonics offers Doppler velocity and imaging capabilities, both of whi ch could be of great value in production logging. Some air-water measu rements, both imaging and velocimetry, are presented, along with a dis cussion of pulsed Doppler theory.
