地震数据体存储格式研究

The research on the storage format of seismic data volume

随着高精度地震采集技术和大连片处理技术的发展,地震处理资料的数据量越来越大,在普通微机上运行传统的基于SEG—Y格式的地震数据体,在抽取显示剖面的效率方面受到挑战。本文打破了传统的存储方式,学习并应用了一种新的数据体格式LDM。通过LDM文件的存储格式、特点以及转换原理,实现了各种地震剖面的高效率抽取。

With the development of the high precision seismic acquisition technology and block-jointed seismic data processing technology, the data volume of seismic processing data becomes larger and larger. The seismic data volume based on traditional SEG-Y format on ordinary computer will be up against the challenges in withdrawing and displaying efficiently the seismic section. In the paper, LDM, a new data volume format is applied instead of traditional storage mode. The high efficiency withdrawings seismic sections are obtained by the storage format, characters and conversion principle of LDM document.
