Morozov Y. Theory and design methods for the systems of subsurface Earth heat extraction, accumulation and utilization

Object of research: thermal and hydrodynamic processes in production systems for deep heat of the Earth utilization and underground heat accumulators. Purpose of work: Developing theoretical foundations and methods for physical and technological parameters calculation of production systems utilizing deep heat of the Earth and underground heat accumulators. Methods of research are based on scientific foundations of the theory of heat conduction, underground hydromechanics and mathematical analysis. Theoretical and practical results. Innovations: for the first time ever on the basis of proven filtering differential equation there was developed a mathematical model of thermal and hydrodynamic processes during fluid flow in deep permeable formations; for the first time ever there was developed a method determining optimal distance between injection and production wells geothermal circulation systems; for the first time ever there was developed a method to calculate multi-mode operation process for underground heat exchangers or heat accumulators. Object and degree of introduction: in Medvedevskyi local authorities, "Innovation Centre of Alternative Energy "Krymgeotermiya" Ltd., State Service of Geology and Mineral Resources of Ukraine, KB "Yuzhekogeotcentr" UkrGGRI, Research oil and gas center.Efficiency of introduction: saving fossil fuels. Utilization field: geothermal energy.
