Fyk M. Theoretical fundamentals of heat and mass exchange processes of geothermal fluids rational extraction of hydrocarbon wells.

In the dissertation work the actual scientific and practical problem of development of theoretical bases of rational extraction and logistics of geothermal resources of wells of oil and gas fields on an example of the Dnieper-Donetsk basin which consists in application of combined extraction of "fluid-geothermal heat" of a phenomenological model that reflects the sequence and relationship of all elementary subprocesses of such extraction of fluid-geothermal resources, development of mathematical models of these subprocesses and on their basis - a mathematical model of the combined process of extraction of "fluid-geothermal" as a whole. The rational geometric topology of heat exchangers is substantiated and the regularities of effective extraction of geothermal energy from the reservoir of oil (gas) and the near-space, its conduction through the transition clogging zone "formation-bottom of the well" and energy lifting to the well and transport system are established consumer taking into account the properties of lateral rocks of wells, reservoirs, heat carriers, structure of underground heat exchanger, circuitry of efficient extraction, accumulation and storage of energy resources, geological and technological features of oil and gas condensate fields, in particular, the Dnieper-Donetsk basin - and heat productivity of oil and gas and depleted reservoirs, which is aimed at the implementation of combined production of "fluid - geothermal heat" as a dual-combined technology. The performed work can be used for creation and development of domestic downhole geothermal-hydrocarbon energy of innovative type. In addition, some of the results can be used to intensify energy production and continue the operation of unprofitable hydrocarbon wells.
