Method of eliminating the effect of a free gas on the measurement of water cut three-phase oil-water emulsion by the flow microwave water-cut meter

Abstract

A method is proposed for eliminating the influence of free gas on the measurement of the water-cut of a three-phase oil-water emulsion (OWE) with an in-line microwave water-cut meter by in-troducing a specialized statistical processing of the current water-cut meter readings. The useful effect is to increase the accuracy of water cut measurements and to reduce the requirements for degassing the OWE at the stage of preliminary preparation. Additionally, it is possible to esti-mate quantitatively the extent of homogeneity violation of the working environment.
