摘要
标准地震资料数据是以SEG Y文件流的方式存储的,直接使用这种格式的数据进行三维地震解释,会使系统的大部分资源耗费在SEG Y格式数据转换上。为了提高数据的访问效率,必须对这种数据进行格式转换,并以能够高效访问的文件的形式存储在硬盘上,访问时以数据页的格式调入内存。详细论述了数据格式的转换方法,同时对存储和访问技术给出了具体实现。
SEG Y file stream is a common storage format of standard seismic data. Most of system time would be wasted on format conversion if this sort of data were processed for 3-D explanation seismic directly. So pretreatment is necessary. Data must be constructed into files that can be accessed efficiently and read in memo- ry as data pages momentarily if necessary. Conversion methods were discussed in detail in this paper. Simultaneously, concrete storage technique was given for high efficient access of data.
