多层油资源运移聚集并行数值模拟,其功能是重建油气盆地的运移聚集演化史,对于油资源的评价,确度油藏位置,估计油藏贮量均具有重要的价值.从生产实际出发,提出数学模型,构造大规模精细并行计算的耦合算子分裂隐式迭代格式,设计了并行计算程序和并行计算的信息传递和交替方向网格剖分方法.并对不同的网格步长进行了并行计算和分析.对滩海地区进行精细数值模拟,计算结果在油田位置等方面和实际情况相吻合.对模型问题(非线型性耦合问题)进行数值分析,得到最佳阶L2误差估计,解决了这一计算渗流力学和石油地质的困难问题.
Multi-layer oil migration and accumulation parallel numerical simulation, its function is to rebuild the evolution history of migration and accumulation of oil and gas basins, for the evaluation of oil resources, the accuracy of the reservoir location, the estimated reservoir reserves are of great value.From the actual production This paper puts forward the mathematical model and constructs the coupling operator splitting implicit iterative scheme for large-scale fine parallel computation, and designs the parallel computing program and parallel computing information transfer and alternating directional meshing method. And carried out the parallel calculation and analysis.The detailed numerical simulation of the beach area coincides with the actual situation in the field of oilfield.The numerical analysis of the model problem (nonlinear coupling problem) It is estimated that this difficult problem of calculating seepage mechanics and petroleum geology has been solved.
