摘要
Richer AVO attributes information can be extracted with the continuous improvement of the AVO crossplot and the advancement of superimposed inversion technology.The variation of reservoir thickness and Poisson′s ratio is analyzed intuitively on the crossplot combined with the oil and gas physical meaning of the two attributes and their relationship.The anomalies of oil and gas or lithology are identified and explained according to some priori information.In this paper,the influence of reservoir thickness and Poisson′s ratio on the AVO crossplot are analyzed with appropriate selected parameters which results in obvious rules and good results.
