SYSTEM OF MEASUREMENT OF COMPONENT-WISE MASS FLOW RATE OF THREE-COMPONENT FLOW OF OIL WELLS Russian patent published in 2008 - IPC G01F1/74 G01N22/00 G01F1/86 E21B47/10 

FIELD: physics, measurement.

SUBSTANCE: invention may be used for control of oil wells debit. System contains two high frequency resonators installed on dielectric pipe, every of which represents short-circuited conductor in the form of meander with two mutually orthogonal inlets-outlets, short-circuited limiting and limiting-separating coils, Coriolis acceleration flow meter with electronic transducers of flow and density, pressure sensor and temperature detector, computer control unit, controlled high-frequency generator and switching device, controller of flow modes, the first and the second controllers of Coriolis acceleration flow meter, two input amplifiers, four transmitting tracks and eight dividing condensers. Relative volume content of flow components is measured on the basis of method of high-frequency probing of flow in two mutually orthogonal directions, method of autocorrelated measurement is used to measure flow rate, and Coriolis acceleration flow meter and calibration controllers are used for measurement of mass flow rate and density of controlled medium. Selection of valid calibration makes it possible to perform precise measurements of mass flow rate and medium density in unstable condition of non-uniform gas-liquid flow.

EFFECT: provision of accurate measurements of mass flow rate and density of medium.
