盆地发育的运移聚集史数值模拟,其功能是重建油气盆地的运移聚集演化史,它对于油资源的勘探,确定油藏位置和计算油藏贮量,寻找新的油田,具有极其重要的价值.从渗流力学和地质科学实际出发,研究了三维(带断层和通道)多层问题的渗流力学和石油地质非线性特征,提出一类迎风分数步隐式迭代格式,对胜利油田东营凹陷、惠民凹陷、滩海地区和阳信洼陷的实际问题进行数值模拟试验,结果和实际地质情况吻合.对模型问题,得到数值方法收敛性,成功解决了这一重要问题.
The numerical simulation of the migration-accumulation history of the basin development has the function of reconstructing the evolution history of hydrocarbon migration and accumulation in the oil-gas basin. It is extremely important for exploration of oil resources, determination of reservoir location, calculation of reservoir reserves and search for new oilfields Value.From the perspectives of seepage mechanics and geosciences, the seepage mechanics and the characteristics of non-linearity of petroleum geology in the multi-layer three-dimensional fault zone with channel faults are studied. A new type of step-by-step implicit iterative windward fractionation method is proposed, Huimin depression, beach area and Yangxin depression. The results are in good agreement with the actual geological conditions. For the model problem, the convergence of the numerical method is obtained and this important problem is successfully solved.
