METHOD FOR MEASUREMENT OF FLOW RATE OF TWO-PHASE THREE-COMPONENT MEDIUM Russian patent published in 2014 - IPC G01F1/20 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry and namely to the methods of oil well debit determination without preliminary gas separation from the well production. The method for measurement of flow rate of two-phase three-component medium involves calibration of a multiphase flow meter, processing of results of calibration works, synthesis of mathematical model of two-phase three-component medium movement, determination of interval of flow rate of liquid and oil gas at which there is an allowable error for calculation of flow rate of oil, water and oil gas. At that in process of calibration works and synthesis of mathematical model of two-phase three-component medium movement dependency of calibration point error is determined on the average weight of points in the teaching model an in process of the well operation sensor readings are recorded for the multiphase flow meter and calculation of the product flow rate is made for components of the oil well at the average weight of points in the teaching model when at calibration points a minimum value of root-mean-square deviation is observed between the calculated and measured values of fluid rate.

EFFECT: reducing error in measurement of the flow rate by components for the oil well product.
