FIELD: oil and gas industry.
SUBSTANCE: group of inventions pertains to monitoring of parameters for wells with wellhead and bottomhole equipment. More specifically these inventions specify the system and method for determination and calculation of the well flow rates produced by electric submersible pumps. The invention concept is as follows: the method for determination of flow rate through electric submersible pump contains stages with the following operations: supply of electric energy to an electric submersible pump from the surface distributing unit; readout of intake pressure by means of processor at the first pressure gage from the well bore bottom in regard to the electric submersible pump and pressure at the output of the second pressure gage; readout of voltage and current values by means of the processor; readout of at least one static value by means of the processor; calculation by means of the processor of flow rate passing through the electric submersible pump, whereby ratio of efficiency factor to the flow rate is calculated with entry of read voltage and current values into power equilibrium equation; non-dimensional flow rate is obtained with entry of the calculated ratio of efficiency factor to the flow rate into statistic data; flow rate is calculated on the basis of non-dimensional flow rate and diagram of calculated flow rates is drawn.
EFFECT: improving efficiency of monitoring.
