dc.description.abstractResearches the physical properties of the mixture of water underground and gases is investigated in this paper. Also paper analyzes an existing geothermal energy extraction system, which consists of a long pipe system and a large number of hydraulic and mechanical elements. The mathematical model of the geothermal system “depth centrifugal pump-pipe (pipe system)” was made to assess the characteristics of an extraction depth centrifugal pump and their correlation with impeller frequency, discharge and other system parameters. Based on this mathematical model the instability zones of the system were determined. A universal mathematical model of depth centrifugal pump was made. This model could be used to describe hydrodynamic processes of injection pumps in the pipe systems, where large amounts of released gases influences the productivity of the pump and geothermal energy extraction system overall.
