深反射地震剖面技术以其探测精度高的优势被作为岩石圈精细结构研究的先锋技术,并取得了突飞猛进的发展.但是,因为探测剖面长,地表地形复杂等原因,对深反射地震数据处理的改进一直是地球物理学家关注的关键内容.近十几年来,随着探测工作量的增加和处理技术的发展,涌现出不少新思路用以深地震反射数据处理,特别在静校正、速度分析、去噪和一致性处理等重要环节更是优化了原处理技术,提升了深反射地震数据处理的水平.本文阐述了深反射地震数据的基本特点,结合实例对当前深反射地震数据处理中使用的主要技术进行了系统的总结,对比了一些方法的优缺点,并对深反射地震数据处理技术的未来发展方向进行了展望.
With the advantage of high detecting precision, deep reflection seismic profile is known as the leading technology of lithosphere fine structure study, and has developed rapidly in recent years. However, due to the long seismic profile, the complex surface and topography, how to improve the deep reflection seismic data processing has always been the key issue paid more attention by Geophysicists. In recent ten years, along with the more detection workload and the processing workflow development, a lot of new ideas has emerged in deep reflection seismic data processing, especially in some important processing stage, such as statics, velocity analysis, noise attenuation and surface consistent processing, which have been optimized to upgrade deep reflection processing level based on the legacy processing workflow. The basic feature of deep seismic data is stated in this paper, meanwhile we systematically summarized the main solutions of current deep reflection seismic processing, compared the advantage and disadvantage of some processing solutions, and forecasted the future vision of deep reflection seismic data processing's development direction.
