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.
Deep reflection seismic profiling technology has been used as a pioneer in the research of fine structure of lithosphere for its high detection accuracy, and has achieved rapid development. However, because of the long profile and complicated surface topography, deep seismic reflection data processing Improvement has always been a key concern of geophysicists.In recent ten years, with the increase of exploration workload and the development of processing technology, many new ideas emerged for deep seismic reflection data processing, especially in static correction and velocity analysis , Denoising and consistency processing and other important aspects is to optimize the original processing technology and enhance the level of deep reflection seismic data processing.This paper describes the basic characteristics of deep reflection seismic data, combined with examples of the current deep reflection seismic data processing used The main technologies are summarized systematically, the advantages and disadvantages of some methods are compared, and the future development of deep reflection seismic data processing technology is also forecasted.
