The traditional AVO theory only considers the petrophysical characteristics of strata on both sides of the single
interface,without considering the layer thickness,seismic wave attenuation and velocity dispersion．Here,we utilize
layered media Brekhovski equation for rock physical forward modeling which takes layer thickness and the impact of
seismic wave domain-frequency into account,and regards it as the theoretical guide for AVO analysis.By combining
wavelet frequenct-division technique with AVO analysis,we study the AVO gradient variation of reflection amplitude
of seismic wave in different frequency band to solve the AVO identification and prediction problem for thin-
interbedded reservoir.By the application in Luojia Area,we conclude a practical workflow of prestack frequency-
division AVO analysis.Through adopting the workflow,the distribution of thin-interbedded Es1 Biolithite reservoir is
effectively predicted.
