摘要： 地震AVO （amplitude versus offset）技术是一项利用振幅信息研究岩性、检测油气的地震勘探技术。常规方法基于Zoeppritz方程计算模型界面处的反射系数，而实际地下非均匀介质中地震反射特征不仅与入射角度、物性差异有关，还与入射波频率、地层厚度、薄互层结构等因素有关。为此，应用传播矩阵理论充分考虑与这些因素有关的调谐干涉等传播效应，针对实际数据计算非均匀地下介质的高精度合成地震记录，对比Zoeppritz方程、Shuey二项近似方程、Shuey三项近似方程以及传播矩阵算法的模拟效果。研究发现：在小角度入射时Zoeppritz方程、Shuey二项近似方程和Shuey三项近似方程的反射振幅和波形基本一致，大角度入射时Zoeppritz方程与Shuey三项近似方程接近；Zoeppritz算法的模拟结果在小角度入射和浅层情况下与传播矩阵算法差别较小，而在大角度入射和深层情况下与传播矩阵差别较大，说明层间多次波的调谐干涉等传播效应不可忽略。

Abstract: AVO (amplitude versus offset) is a technique for studying lithology and detecting hydrocarbon seismic exploration by using amplitude information. Conventional single interface reflection coefficient can be calculated by Zoeppritz equation; however, the reflection characteristics of layered media seismic wave is not only related to incident angle, but also differences of physical property, incident wave frequency, formation thickness, thin interbedded structure, the formation non-uniformity and other factors, and all the factors related tuning effects are fully considered in the theory of propagation matrix. Based on the data calculation of high-precision synthetic seismogram in heterogeneous underground media, we compared the simulation results of Zoeppritz equation, Shuey two-term approximation equation, Shuey three-term approximate equation, and propagation matrix algorithm. The study shows that at a small incident angle, the reflection amplitude and waveforms of Zoeppritz equation, Shuey two-terms, and Shuey three-term approximation are basically the same; while at a large incident angle, those of Zoeppritz equation and Shuey three-term approximation are closer. Under the condition of small incident angles and shallow layers, the seismic responses of Zoeppritz equation and propagation matrix algorithm is almost the same, but different at large incident angles and deep layers. It is illustrated that the tuning effects and multiple wave interferences cannot be ignored.
