摘　　要：地震资料处理集群系统是石油勘探领域规模最大的计算机应用系统,通过对地震资料处理集群系统软硬件架构描述和各组成部分功能及应用技术的介绍,详细分析了系统性能包含的因素。提出应从硬件容量、软件环境、网络通讯三个方面定位集群系统作业性能下降的原因。结合运维中的一则实际案例,详细描述了该类问题的排查思路、设计方案、使用工具及测试结果。为今后同类系统的维护、故障排查提供可借鉴经验。The seismic processing system is the largest scale computer application system in petroleum exploration field. Through describing software and hardware architecture of seismic processing system, which includes every part＇ s function and applied IT technology, this paper detailedly analyses the all factors which can effect the performance of seismic processing system. It points out that reason study on the performance reduction is mainly from following three aspects： hardware capability, software configuration and network communication. By connecting with actual case in operational maintenance, it gives out the resolving thinking method, designing scheme, using tools and test result. It can provide the referential experience for troubleshooting of other seismic processing cluster system.
