| 摘 要： | 区域分解方法是适应并行计算机的工作原理应运而生的偏微分方程数值算法，将它应用于解决三维实际问题且行之有效的并行软件并不多见．本文基于共享内存多处理机并行系统解决一类三维黑油油藏数值模拟问题，分别给出了子结构类型ＤＤＭ和Ｓｃｈｗａｒｚ类型ＤＤＭ两种区域分解方法的并行算法，并进行了比较，就它们在实际应用中的区域划分对收敛速度及计算时间的影响进行了讨论

| Abstract: | In this paper,two domain decomposition methods on shared memory parallel computer systems for solving a black numerical simulation of reservoir are given. We also discusse the influence of domain division on convergence speed and computation time in practical production.The practical results show that Schwarz type DDM algorithm and substructure type DDM algorithm are effective in numerical simulation problem of reservoir,and can increase in speed. |
