METHOD FOR MEASURING FLOW RATE OF PHASES IN GAS-LIQUID STREAM Russian patent published in 1998 - IPC

Abstract RU 2105145 C1

FIELD: oil and gas production industry. SUBSTANCE: this is intended for separate measurement of flow rates of dual-phase streams from producing oil, gas, and gas-condensate wells. Method is based on calculating root-mean-square value of pulsing pressure signal in two informative frequency ranges. Additionally determined are functional coefficients of gas-content flow rate, and according to product of corresponding root-mean-square value of pressure pulsing multiplied by corresponding functional coefficient, determined is flow rate of phases in gas-liquid mixture. This improves accuracy of separate measurement of output from oil-gas wells as to liquid and gas in conditions of varying gas content in wide limits. EFFECT: high efficiency. 4 dwg
