摘要
在高密度、大道数的三维勘探项目中,无线节点仪器进行连续数据记录,具有接收道数多和炮数多、观测时间长、采集的数据量大的特征。数据处理过程对服务器和磁盘阵列的访问会产生大量的数据请求、发送、读取和存储。本文从服务器高并发、多线程管理的线程池、磁盘阵列与服务器连接方式、地震数据读写算法四个方面,探讨了限制数据处理速度的环节。提出相应的配置策略与实现方法,实现地震数据的高速处理,对野外物探数据快速处理具有普适性。
In the 3D exploration project with high density and large number of channels,wireless node instruments record continuous data,which has the characteristics of more channels and more shots,long observation time and large amount of data.Access to servers and disk arrays by data processing generates a large number of data requests,sends,reads,and saves.In this paper,four factors that the high concurrency performance of the server,the thread pool of multi-thread management,the connection mode between the disk array and the server and the seismic data reading and writing algorithm are discussed which limit the data processing speed.The corresponding configuration strategy and implementation method are proposed to realize the high-speed processing of seismic data,which is universally applicable to the rapid processing of geophysical data in the field.
