Численное моделирование процесса внутрипластового горения при закачке воздуха в пласт

The results of numerical studies of the in-situ combustion problem with an integrated approach are given. This approach involves addition of supplemental relations to a mathematical model for a preliminary analysis of thermochemical parameters of oil according to oil composition. Finite-volume method is used for a numerical solution of a combustion zone propagation problem. Temperature, saturation, concentration of components are calculated by an explicit scheme, pressure by an implicit scheme. In this work, we presented results of numerical simulation of the in-situ combustion process for different parameters of oil oxidation. The dynamics of an oil self-ignition process depending on oil properties is shown.
