RESEARCH OF "LABYRINTH-STYLE" HYDROCARBON MIGRATION AND ACCUMULATION SIMULATION BASED ON THE CORNER POINT GRID MODEL

Considering the actuality of hydrocarbon migration and accumulation simulation (HMAS), the paper established 3D geological model of the petroleum basin based on the Corner Point Grid Model (CPGM). On the basis of studying the migration and accumulation conditions of the oil and gas to be in equilibrium in different geology environment, using HMAS parameter calculation method of the predecessors and adopting the combination mode of Darcy's law and artificial intelligence algorithms to calculate the hydrocarbon migration velocity, the author proposed the "Labyrinth-Style" HMAS idea and programmed the independently running module. This module has been tested in the actual exploratory area—the Dongying Sag in Bohai Bay Basin, the maturing exploratory area of Shandong Province. The satisfactory results have been obtained. The research achievement provides a good analysis tool for decreasing the risk of the petroleum exploration.
