In the processes of development, production and transportation of high-viscosity oils, such as the Kenkiyak fields, there are certain problems associated with the composition and solidification of raw materials at a certain temperature. In this regard, in order to increase the efficiency of the above processes, it is necessary to select appropriate technologies that provide optimal temperature conditions. At present, one of the most effective methods for solving these issues is the use of mathematical modeling to search for, determine the optimal parameters of oil development and production processes based on modern computer and information technology tools. Therefore, in order to effectively solve the problems of development and production of high-viscosity oils, the issues of constructing mathematical models of oil deposits, taking into account their geological and petrophysical characteristics, are an urgent task of oil science and practice. To study the geological models of the studied reservoirs of the Kenkiyak oil field and to develop its mathematical model, methods of system analysis are used. These methods make it possible to apply a set of interrelated methods of geological exploration and determination of oil reserves, as well as methods of forecasting and mathematical statistics in the development of models of the studied horizons of the Kenkiyak field. Based on the results of the study of 4 geological models of the selected main plateaus of the Kenkiyak field, a mathematical model was developed for it, which allows taking into account the dynamics of the movement of the oil mixture during the development and production of high-viscosity oil. The proposed mathematical model is based on the heat-producing model and includes mass and energy conservation equations, as well as mass and oil saturation limitation equations. The results of the study can be used to determine: the permeability of oil reservoirs; oil reserves; optimal temperature conditions and to optimize other parameters of oil production processes.
