摘　　要：应用三维模拟技术,强化油气成藏体系动态演化过程,采用"正反演结合"的思路,探讨叠合盆地油气成藏体系的研究思路和方法。研究过程分五步:通过成藏要素研究构建地质模型;通过正演烃源岩生烃过程与时空演化,分阶段计算生烃量;通过输导体系研究来调整油气最终的分布;应用油气组分追踪技术分析不同烃源岩层贡献比例;根据三维模拟结果动态分析资源空间分布及变化过程。In the paper,it uses three-dimensional simulation technology,which shall strengthen the dynamic evolution of the petroleum accumulation system. Based on the thought of forward and inverse,it introduces the research thinking and methods of the petroleum accumulation system in the superimposed basin. The whole research is divided into five steps as follows：establishes geological model by elements of accumulation; calculates the hydrocarbon generating quantity by stages based on forwarding hydrocarbon generation process and time-spatial evolution of hydrocarbon source rocks; adjusts the final distribution of oil and gas through the passage system; calculates the resource ratio of the different source rocks; analyzes the distribution of resources according to the three-dimensional simulation results.
