§1.引 言 油藏数值模拟自从诞生之日起就一直跟随计算机硬件的发展,来满足石油开采业的技术需求,其求解规模越来越大.模拟的主要目的也己从过去的注重油藏整体动态趋势发展到研究地下流体的精细分布状况.这无疑使每次模拟的计算开销越来越大.十几年前,发达国家出现了并行计算环境(共享或分布式的),与此同时一些油藏模拟器开发者就开始研究串行模拟器的并行化.近五年来,我国石油行业先后引进了一些并行计算机,也开始了对80年代中期所引进的源码油藏模拟器的并行化探讨.然而由于并行实现对特定并行计算环境的依赖很
§1. INTRODUCTION Reservoir numerical simulation has been following the development of computer hardware since the day of its birth to meet the technical needs of the oil exploration industry, and its solution scale is getting larger and larger. The main purpose of simulation has also been to focus on reservoirs The overall dynamic trend has evolved to study the fine distribution of subsurface fluids, which undoubtedly increases the computational cost of each simulation. More than a decade ago, parallel computing environments (shared or distributed) emerged in developed countries, Some reservoir simulator developers began to study the parallelization of serial simulators.In the recent five years, China’s oil industry has introduced some parallel computers and also started the parallelization of the source reservoir simulator introduced in the mid-1980s However, due to the parallel implementation of a particular parallel computing environment is dependent on
