METHOD FOR CHANGING MULTI-PHASE FLOW USING ONE HIGH-ACTIVE AND ONE OR MORE LOW-ACTIVE RADIOACTIVE SOURCES

摘要

FIELD: oil and gas industry.;SUBSTANCE: in method for changing multi-phase flow using one high-active and one or more low-active radioactive sources with activity below minimum relevant activity there used is a low-active radioactive source for continuous monitoring of multi-phase flow of separate wells. There performed is a regular measurement of reduction factor of water, oil and gas produced from well via high-frequency measuring device containing high-active source.;EFFECT: increase of efficiency and accuracy of data collection of multi-phase flow, increase of works safety.;8 cl, 2 tbl, 1 ex
