In conventional seismic data processing, the earth is regarded as prefectly elastic medium.However,the pores of stratum rock often contain fluid. So, when the seismic wave propagates in it, there are energy attenuation and phase distortion related to frequency. Moreover, the attenuation, scattering,and dispersion of high-frequency components are far higher than that of low-frequency components.
