Abstract

Spectral decomposition techniques can be used to extract some useful information in time-frequency domain which can not be found in conventional time domain, and improve the prediction ability of thin reservoir and lithologic traps. The key point of spectral decomposition is time-frequency analysis. This paper expounded the principle and method of time-frequency analysis technique and its significance to seismic data processing. Some application cases of time-frequency analysis technique in seismic exploration were presented to illustrate the progress of the application of time-frequency analysis in seismic exploration, including spectral decomposition, spectral inversion, waveform classification and frequency splitting processing. From the process we can see that the application of time-frequency analysis technique
in seismic exploration has a fine prospect.
