METHODOLOGY FOR ESTIMATING HEAT LOSSES DUE TO HEAT EFFECTS ON A HETEROGENEOUS OIL RESERVOIR

Abstract

The problem is now becoming ever more relevant due to a wide variety of practical applications of filtration heat transfer to the solution of the problems of forecasting and regulating the thermal regime in geotechnological systems. In the development of high-viscosity oil fields, thermodynamic effects on the oil reservoir are particularly promising, one of which is the injection of hot heat carriers into the oil stratum. The article deals with the analysis of the main components of the reducing temperature potential process of the coolant under thermal action on a multi-layered oil reservoir. It is noted that not all heat entering the reservoir is useful. The heat spent on warming up the solid phase of all the structural elements of the inhomogeneous deposit should be attributed to losses. Therefore, the underground part of the geotechnological complex with the oil deposit was chosen for the study. The model problem of heat transfer in an inhomogeneous oil reservoir is considered with the aim of obtaining a simple analytical solution for determining the time for heating the reservoir with residual oil to a predetermined temperature allowing it to begin to be displaced. Solving the conjugate problem of non-stationary heat transfer under the conditions of a multilayer filtration scheme, the equivalent heat equation was used, which has a wide application in solving a number of problems of geothermal thermal physics. The implementation of the method made it possible to obtain analytical dependencies for analysing the temperature fields of oil deposits with a multilayered heterogeneous structure. The results presented in the form of graphical dependencies in dimensionless variables make it possible to use them for various initial parameters of the problem.
