-
摘要: 从油气运聚模拟的现状出发,基于角点网格模型建立了油气盆地三维地质模型。研究了油气在不同地质环境下达到平衡态的运移条件和存储条件,继承前人总结的油气运聚模拟参数计算方法,采用达西定律和人工智能算法相结合的方式计算油气运移速度。在此基础上,提出了"迷宫式"油气运聚模拟思路,并编码实现,形成了一个可以独立运行的油气运聚模拟模块。运用该模块对渤海湾盆地东营凹陷勘探成熟区进行了模拟试验,得到了较为理想的效果。其研究成果,为降低油气勘探风险提供了很好的分析工具。Abstract: 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.
