Abstract

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.
