地震勘探中超万道SPS文件整理方法

SPS file preparation method for over ten thousand trace in seismic exploration

高密度大道数(三维)地震勘探的应用日益增多,也给野外地震数据采集施工带来了新的挑战,如现行SPS整理软件及标准不支持大道数地震数据采集。本文针对超万道地震勘探中SPS文件整理方法进行了探讨:首先分析了超万道SPS文件与常规SPS文件的区别,以及超万道采集中现行SPS定义格式中出现的问题;然后对超万道SPS文件格式进行分析,总结出超万道SPS文件整理方法,并介绍了超万道SPS文件整理软件的开发与实现;最后将文中论述的超万道SPS文件整理方法应用于实际地震数据处理,取得了较好的效果。

There are more and more high density and large trace number(3D) seismic exploration application,which brings new challenge for the field seismic acquisition,for example the current SPS software does not support large trace number acquisition.The SPS file preparation method for over ten thousand trace in seismic exploration was discussed in this paper,at first the difference between the conventional SPS file format and the SPS file format for over ten thousand trace was compared,then the problem for using the conventional SPS file format in acquisition for over ten thousand was analyzed,thirdly the SPS file format was analyzed and summarized,and fourthly the development and realization of the SPS file preparation software for over ten thousand trace were introduced,and at last the SPS file preparation software for over ten thousand trace was used in field seismic data processing,great results were achieved with the method.
