AVO inversion is an important aspect of its techniques which is to make inversion for the varieties of amplitude versus offset based on the normal pre-stack common reflection gathering and extract compressional wave, shear wave and density.

• AVO反演是AVO技术的重要组成部分,它是对常规叠前共反射点道集的振幅随炮检距变化进行反演,提取纵、横波速度和密度,AVO反演不同于其它地震反演。
