|Abstract:||It is shown in the work that the wells-fluid are extracted from rocks by heat-retaining fluid from the open geothermal reservoir as from object with distributed cross-sectional parameters. This is due to the fact that the actual temperature distribution of the geothermal reservoir in dynamics affects the thermal properties of fluid-retaining rocks, which in turn affect the coefficient of heat exchange and heat transfer along the cross-section between the moving fluid, the fluid-retaining layer and adjacent rocks. The static temperature field of the original geothermal gradients in the case of outflow injection of the circulating coolant changes from the sides of the reservoir to the wellbore. A model of geothermal reservoir of gas-condensate well has been developed, which takes into account changes of thermal conductivity of rocks from the reservoir counture to the well bottom. The model includes refined equations of thermal energy balance for radial filtration of well production, containing convective and conductive components of heat exchange and heat flow. This allows, in comparison with the known methodological approaches, to clarify by 12-14% the forecast of heat extraction from a geothermal reservoir with a circulating coolant thrue the bottom and productive layer of a gas-condensate well.|
