METHOD OF RESEARCH OF INJECTION WELLS Russian patent published in 2019 - IPC E21B47/10 G01F1/80 G01F15/08 

FIELD: measurement technology.

SUBSTANCE: invention relates to methods and a measuring complex for studying a mixed flow of gas, liquid and solid particles. Method of research of injection wells, where one or several wells are acceptors, and one or several wells are donors, on which the nozzle is installed, produced as a result of simultaneous measurement of the well flow rate of fluid, injectivity and injection pressure, using pressure measurement before and after fitting with a differential pressure gauge, both measuring chambers of which are connected by high-pressure hoses, one of which is connected to the valve before fitting, and the other is connected to the valve after fitting, where the internal space of the nozzle and the pipeline section is used as low pressure and high pressure chambers.

EFFECT: improving the accuracy of measuring the flow of multiphase fluid.
