PAN style="FONT-SIZE: 14pt" lang=EN-US>On the basis of traditional wavelet deconvolution algorithm, the authors designed an improved wavelet deconvolution algorithm. By filtering of logarithmic power spectrum of seismic records, this algorithm could not only recognize BSR (Bottom Simulating Reflector) effectively, but also overcome the influence of non-white noise. It is simple and convenient to extract wavelet by Hilbert transform algorithm. Seismic data of northern South China Sea line HS621 processing with improved wavelet deconvolution algorithm shows that the algorithm can not only track BSR stably and clearly, but also can effectively improve the seismic data resolution to meet the natural gas hydrate seismic data fine processing.
