Abstract

Hydrodynamic and thermodynamic processes of geothermal well extraction are investigated and presented in this article. Mathematical models were developed for a deep suction multi-stage centrifugal pump and a piping system. The mathematical models were used to evaluate the gas (nitrogen) release from fluid and its effect on hydrodynamic processes. Through conducted experimental research and by applying mathematical modelling, it has been observed that the gas content in fluid increases the pressure and flow pulsations within a deep multi-stage centrifugal pump. Variation in height of a water column during the process of extraction has influence on characteristics of multistage centrifugal pump in wells.
