Annotation:

Dynamic vane pumps for oil production are characterized by supply and pump head, which, in some cases, allows assessing the possibility of using this equipment in certain operating conditions. However, when working on a gas-liquid mixture, determining the pump head in both bench and field conditions becomes a difficult task due to the uncertainty of the mixture density with changes in pressure, temperature, volume gas content and other parameters. At the same time, the values of pressure and liquid supply in the nodes of the well - pumping unit system can be quite simply determined and become the basis for constructing the characteristics of the pump in the "supply-pressure" coordinates. The paper raises the problem of the legality of replacing the working indicator "pump head" adopted for dynamic pumps with the indicator "pump pressure", as a more universal and meeting the requirements for improving the accuracy of its determination. This, in turn, will lead to an increase in the efficiency of monitoring, modeling and digitalization of mechanized oil production facilities.
