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
The method of regional decomposition is a numerical method of partial differential equations that is adapted to the working principle of parallel computers. It is rare to apply it to the practical problems of solving three-dimensional problems. In this paper, based on the shared memory multiprocessor parallel system to solve a class of three-dimensional black oil reservoir numerical simulation problems, two parallel subdivision methods of DDM and Schwarz type DZM are given respectively and compared with each other. The influence of regional division on convergence speed and calculation time is discussed
