METHOD FOR DETERMINING PHASE FLOW RATES OF GAS-LIQUID MIXTURE IN PRODUCING WELL Russian patent published in 1997 - IPC

FIELD: geophysical investigation of producing wells. SUBSTANCE: method relates to quantitative evaluation of phase flow rates in intervals in conditions of gas-liquid product. Method implies measuring along well axis of barogram in sensitivity scale, separation of zones with stable plugging structure of gas-liquid flow between intervals in delivery of fluid from beds into well hollow. Then recorded in aforesaid zones are fluctuations of pressure parameter at fixed points, and determined according to amplitude and frequency spectra of recorded signals are size of gas plugs and frequency of their occurrence which are used as indications of changing phase flow rates according to depth, and of distribution of phases according to depth. Method allows for improving truth in determining both summary and interval phase flow rates of gas-liquid mixture in producing oil-gas wells. EFFECT: high efficiency. 3 dwg
