MEASURING METHOD OF TOTAL AND FRACTIONAL FLOW RATES OF NON-MIXED MEDIA AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G01F1/74 

FIELD: measurement equipment.

SUBSTANCE: invention proposes a measuring method of total and fractional flow rates of multiphase and non-mixed media, which involves scanning of a flow of multiphase transported medium in a test section with a high-frequency electrical field, processing of scanning results, determination of amplitude-frequency characteristics and determination on their basis of fractions in the flow of the multiphase medium and sound velocity for this flow of multiphase medium. In addition, the flow of the transported multiphase medium is scanned with an ultrasonic beam and pipeline flow velocity is determined using Doppler shift of frequencies of direct and reflected ultrasonic signals and a certain sound velocity. By using measurement results of the flow velocity and fractional composition, fractional and total flow rates are determined in the flow of multiphase transported medium. The invention also proposes a system for measurement of total and fractional compositions of multiphase non-mixed media in a pipeline, which implements this method.

EFFECT: possibility of prompt control of flow rate of oil wells considering a real situation at the moment of measurements.
