【Abstract】 A new metod of finding amplitude ratio profile is developed based on prestack kirchhoff integral migration. The patterns of amplitude profile varying with parameters are analyzed. In addition, the geologic interpretation to the profile of amplitude ratio is discussed. Through the processing and interpretation to seismic data of Zhungeer basin, the validity of using the amplitude ratio profile to identify the interface of stratum and lithology is verified, which has provided a valid auxiliary means for seismic processing and interpretation.更多还原
