The invention discloses an online measurement and calibration device for oil-gas-water multiphase flow, which comprises a single-phase oil calibration
system, a single-phase
water flow calibration
system, a single-phase gas flow calibration
system, a heating
buffer tank, a
screw pump, a static mixing device, standard meter, meter to be tested,
pressure sensor, first temperature sensor, first regulating valve, first
ball valve, separator, first quantitative
plunger pump, second quantitative
plunger pump, the device realizes modularization Management,
fully automated operation, used to simulate the flow pattern, flow rate and ratio of the three-phase flow of oil, gas and water at the oil and gas
wellhead; it can realize single-phase oil flow, single-phase
water flow, single-phase gas flow, gas-liquid Two-phase flow rate, oil-water two-phase flow rate, oil-gas-water three-phase flow rate, oil-water two-phase flow separation
phase holdup, oil-gas-water three-phase flow separation
phase holdup calibration, calibration and other functions to simulate the working conditions of real oil wells , to provide experimental support for the development of multiphase flow metering instruments.
