Shuey, the paper obtained more accurate zero-offset reflectivity by fitting reflectivity changed with incident angles, which improved the signal-to-noise ratio of seismic data,while did not fundamentally change the relationship of reflected amplitudes changing with offsets in original CMP gathers of seismic data that can further inverse the accurate section of AVO attributes.
本文从Shuey的佐普里兹方程近似式出发,通过拟合随入射角变化的反射系数,获得较精确的零炮检距反 射系数,提高了地震资料的信噪比;而且这种拟合方法不会从根本上改变原有地震资料CMP道集上反射振幅 随炮检距交化的关系,进而反演出较准确的AVO属性剖面。
