Effect of Convective Transport in Porous Media on the Conditions of Organic Matter Maturation and Generation of Hydrocarbons in Trap Rocks Complexes

By analyze of catalysis processes of hydrocarbons and oil in the medium with the oil source rocks usually it is used the approximation about homogeneous medium and homogeneous РТ- conditions in it. But the oil source rocks are porous medium, the slow flows in which are influenced by convection, which leads to significant heterogeneities of the structure of РТ- conditions of oil source matter ripening. These structures can be either stationary or no stationary. In that paper we developed results of numerical modeling of convection in homogeneous medium and in the medium that contains heterogeneous for permeability 2D and 3D inclusions for detection and quantitative estimation the convection influence on the volume oil source rocks estimation in which the oil catalysis conditions are realized. It is showed that the amount of oil forming significantly depends from the convection intensity.
