在油气成藏动力学模拟评价系统的基础上,进一步考虑各种地质因素,包括快速底层数据建模、模拟数据的透明化、油气初次运移模型、多因数控制的油气运聚模拟、油气最优运移路径的法线追踪等,建立了地质模型,并将地质模型转化成数学模型和计算机模型,提升了该系统的模拟能力,使该系统成为地质学家的一个油气系统三维可视化分析工具.利用该系统对东海盆地丽水凹陷开展了实际应用,得出丽水凹陷总生烃量为158×108t,其中生油78×108t,生气79×1011m3,从而对该凹陷的油气勘探起到了指导作用.

Based on the petroleum pool-forming dynamics simulation and evaluation,the more geologic factors have been considered,such as quick basal geologic data modeling,querying and editing for the simulation,the primary migration model,the multi-factor oil and gas accumulation simulation and ray-tracking oil and gas migration method and so on.The geologic models have been made,and transferred farther into mathematic and computer models.Therefore,the system can be acted as 3D visual analytic tool for oil and gas migration and accumulation.The system has been made application for the Lishui Sag,the East China Sea Basin,this simulation result has been approbated for integrated research team of the Lishui Sag,the East China Sea Basin.
