Abstract: 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.
