We have analyzed effect of Poisson's ratio and reservoir thickness on AVO effect with typical three\|layers and multi\|layers media theoretical models, investigated varying characters of AVO effect in various parameters composing conditions and analyzed relations of Poisson's ratio and reservoir thickness with AVO characterized parameters. We obtained inversion expressions of Poisson's ratio and reservoir thickness, made inversions to three\|layers and multi\|layers media theoretical models by making use of these inversion expressions, inversion results approach actual values. Thus we can predict Poisson's ratio and reservoir thickness by means of this method.
