油资源运移聚集并行数值模拟和分析

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.

Parallel Numerical Simulation and Analysis of Migration-Accumulation of Oil Resources

Parallel numerical simulation of migration-accumulation of oil resources in porous media is to describe the process of oil migration and accumulation in basin evolution.It is of great value to the evaluation of oil resources and to the determination of the location and amount of oil deposite.This paper puts forward a numerical model,a parallel operator splitting-up implicit iterative scheme,parallel arithmetic program,parallel arithmetic information and alternating-direction mesh subdivision.It also discusses computation and analysis of different mesh step lengths.For the actual situation of Tanhai region of Shengli Petroleum Field,the numerical simulation test results and the actual conditions are coincident.For the model problem(nonlinear coupled system) optimal order estimates in l~2 norm are derived to determine the errors.The problem in the fields of permeation fluid mechanics and petroleus geology appears to be solved.
