摘　　要：对胜利油区广泛采用的多层二维二相油藏模拟模型开展了并行化研究 ,提出并采用按层粗粒度并行及区域分解并行两种方法实现软件的并行化。模型及实例计算表明 ,并行化的多层二维二相模型具有较高的并行效率。为解决存储及通讯问题 ,采用了压缩存储及压缩通讯技术 ,有效地提高了软件的并行效率。对通讯量、层数、大规模模型应用等因素的分析和大规模油藏模拟的并行化提供了有力的工具 ;The parallelization research of the multilayer, twodimension and twophase model used extensivily in Shengli oilfield reservoir simulation is in progress. The two methods of coarse granularity parallel by layers and domain decomposition parallel are put forward and used to realize the software parallelization. The computation of the model and examples showed that multilayer, twodimension and twophase model possesses higher parallel efficiency. In order to solve memory and communication, the technology of compressed memory and compressed communication is adopted, and increases parallel efficiency of software effectively. It provided powerful tool for factor analysis of communication capacity, the number of layer and largescale model use, and for parallelization of largescale reservoir simulation. It also provided technical support for effective spreading fine reservoir simulation technology.
