Study on spectral modeling deconvolution in time-frequency domain
Online published: 2013-02-20
The energy of seismic wave attenuates continuously in spreading process, and its effective band of frequency amplitude spectrum is striation, which declines the resolution of seismic data. Improved generalized S transform of window function normalized energy holds time resolution constant，and improves the frequency resolution at the same time. Spectral modeling method is drawn in time-frequency domain, in order to avoid the complex window dimension program of the Fourier transform. Spectral modeling method is adapted to the assumption condition that seismic data are smooth and steady signals. Through model experiment and actual seismic data processing, it is proved that this method can improve the resolution of seismic data effectively, which is favorable for thin reservoir identification and fine reservoir description.
