地震资料在FoCUS系统中任意时间段输入/输出的实现
|
摘要
应用在油气探测和天然气水合物研究中的高分辨率采集地震资料,其海量的数据对室内的处理提出了新的难题,不仅降低了对有效数据在磁盘中的使用率,也降低了处理效率。虽然可以通过计算机硬件的升级来提高处理效率,但是我们也应在处理软件方面寻求提高磁盘使用率和处理效率的办法。本文正是根据这个思路,分析了FOCUS地震资料处理系统中最常用的磁盘读写模块DSKRD和DSKWRT,最终修改形成了一对可以读写任意时间段地震道数据的新模块WINDWR和WINRD,在实际资料处理中取得令人满意的效果。
The great capacity seismic data, which apply to the gas exploration or the study in gas hydrate and gathered by high differentiate method, bring forward a new problem to data processing. It not only needs the large disk capacity, but also depresse the processing efficien- cy. We can improve the system performance by upgraded the computer hardware and devices. But we should do it in updating the data processing model. According to this, the article analy- sis the most common disk read-write model, DSKWRT and DSKRD, in FOCUS system, and design a new couple disk read-write -model, WINWRT and WINRD. We got a satisfactory re- sult in the actual data processing application.
