| Abstract: | Three main equations of the numerical simulation system of the hydrocarbon migration are given on the basis of physical essence of petroleum geology process in petroliferous basins, and they are overpressure equation, heat-transport equation and water saturation equation. The theory of simulation and mathematical solution are further discussed. Used the established two-phase and two-dimensional flow model, practical simulation is carried out for some seismic profiles in the northern part of Tarim basin and dynamical evolution messages of formation overpressure, water saturation and flow velocity are obtained. The characteristics of hydrocarbon migration and accumulation are analysed with considering the practical situation. |
