叠前Kirchhoff积分偏移法纵横波振幅比剖面的提取与应用
|
摘要
利用叠前Kirchhoff积分偏移,研究了一种有效的求取振幅比剖面的方法,分析了振幅比剖面随参数变化的规律,并探讨了振幅比剖面的地质解释.对准噶尔盆地实际地震资料的处理和解释证实了振幅比剖面识别地层界面和岩性的有效性,从而增加了一种有效的地震处理解释的辅助手段.
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.
