摘要
Spectral inversion is a method based on the spectral resolution and time-frequency analysis,which can effectively determine the layer thickness below the seismic tuning thickness.In this paper,a global search method——Very Fast Simulated Annealing (VFSA) is used to spectral inversion in high SNR post-stack seismic data.As the presence of noise,in experiment,band spectrum is used in spectral inversion.The result is Quiasi-reflection coefficient.The method expands the bandwidth of the original data,and enhances the data resolution. It is an important role to explain the subtle characteristics in seismic prospecting.
