A mathematical model was developed for calculation of steam-water flow in a geothermal well for the feeding interval. The model assumes a variable mass flow rate over the channel length. The basis for this model are the flow continuity equation, momentum and energy conservation equations, taken with account for variable mass flow. The model was implemented as a computer code suitable for calculation of flow parameters upstream (downward the top level of the feeding zone). Then this model was applied for wells in the Mutnovskii geothermal field, this revealed a geyser-type mechanism of flow instabilities with the pressure oscillation period about ten minutes. The remedy for these oscillations was offered.
