Engineering Physics Annotation << Back DEVELOPMENT OF IDEAS ABOUT TEMPERATURE PROCESSES DURING FILTRATION IN OIL FIELD FORMATIONS A.I. FILIPPOV, N.A. SPIRIDONOVA, A.ZH. ZHYRGALBEKOVA Computational experiments to study the temperature effects that occur during oil filtration at specific fields in Russia have been performed. It is based on a mathematical model of temperature processes developed on the basis of representations of nonequilibrium thermodynamics. New laws have been established for the formation of temperature fields occurring in oil reservoirs after the inflow from the reservoir is called. It is shown that with small depressions, cooling of the productive reservoir is observed, which, with an increase in depression, is replaced by heating. The dependence of the temperature effect on permeability and porosity is investigated. It is shown that with an increase in porosity, the magnitude of the effect decreases, and with an increase in permeability, it increases. The spatial-temporal distributions of the temperature field arising after the start of reservoir operation have been studied. The established regularities are of great practical importance for the study of wells and reservoirs and can be directly used in the interpretation of the results of highly sensitive thermometry. Keywords: reservoir, well, non-equilibrium thermodynamics, temperature field, barothermal effect. DOI: 10.25791/infizik.8.2022.1280 Pp. 21-30.
