网络存储技术在石油地震数据处理中的应用

Network Storage Technology in the Application of Petroleum Seismic Data Processing

针对油田局域网的特点,利用网络存储技术中的SOCKET编程方法,结合Linux或Unix系统中的常驻进程及输入输出控制技术解决海量地震数据交换的问题,这个方法可以实现远程磁带或磁盘数据的读取。对常用的地震数据SEGY格式及其存储特点进行分析,在SEG-Y格式的地震数据的读写技术中,采用位运算的方式解决移位及浮点数的读写操作。网络存储技术的应用实现了远程海量地震数据的存取,位运算方法提高了地震数据输入输出的速度。

On the characteristics of the Oilfield LAN,using network storage technology of socket programming methods,combined with Linux or Unix system of 'daemon' process and input and output control technology to solve massive seismic data exchange problem.Use this method you can implement remote tape or disk data read.Analyse seismic data SEGY format and its storage,in the SEG-Y format seismic data read-write technology,use bitwise operation for floating point numbers.The application of network storage technology for remote access to massive seismic data,the bitwise operation improved seismic data input and output speed.
