Abstract：A set of reservoirs flow rate online monitoring device is developed and it is used in production wells,including a static mixer,flow measurement and phase fraction measurement.Doppler frequency difference is applied to measure total flowrate and two-energy level X ray with no environmental security risks is adopted to measure phase fractions in oil,gas, water three-phase fow and conductance sensors is used to test water fraction quickly in high water fraction three-phase flow. A series of experiments were carried out on the indoor three-phase flow experimental system.Experimental results show that measurement error of water and oil is less than ±7% and gas is less than ±14%.
