摘　　要：研究了地震勘探回波数据的压缩技术,针对地震信号形态纹理明显的特点,采用形态为主、小波为辅的分析方法取代单一的小波分析来研究地震信号的潜在规律,设计了基于形态变换的新一代地震数据压缩算法。With the development of multi-dimensional and high-resolution about seismic exploration technology,and the expansion of seismic data rapidly,the problem of compression is more and more important.The compression technology of seismic exploration echo data has been studied in the paper.The analysis method adopted morphology manly and wavelet assistantly substitutes the single wavelet analysis to the potential rule research of seismic signal aimed at the distinct morphological grain characteristic of seismic signal,and the new generation seismic data compression algorithm based on morphological wavelet been designed.
