通过对美国Ｈａｒｔｚｏｇ Ｄｒａｗ 气田Ｓｈａｎｎｏｎ 储层的地质背景分析，确定了Ｓｈａｎｎｏｎ 储层的外部形态和圈闭类型，描述了其物性特征及分布规律。基于测井资料的ＡＶＯ正演模型指示Ｓｈａｎｎｏｎ 储层的ＡＶＯ 异常具有两类砂岩特征，且油气储层顶部的地震反射振幅随炮检距的改变而发生明显变化，非储层顶部的地震反射无ＡＶＯ异常显示或显示非常微弱。基于地震资料的ＡＶＯ 反演研究进一步证实了该地区Ｓｈａｎｎｏｎ 砂岩储层顶部地震反射振幅随炮检距的改变而变化的规律。这种规律对应用地震资料采用ＡＶＯ 方法进行储层预测具有明确的指导意义。ＡＶＯ技术解决了常规的二维模型不能解决的问题，发挥了ＡＶＯ 的技术优势，在寻找油气藏方面具有实用性和可信性。
By analyzing the geological background of the Shannon reservoir in the Hartzog Draw gas field in the United States, the external morphology and trap types of the Shannon reservoir are determined, and their physical properties and distribution are described. The AVO forward model based on logging data indicates that the AVO anomaly in Shannon reservoir has two types of sandstone features, and the seismic reflection amplitude at the top of oil and gas reservoirs changes obviously with the change of offset. The seismic reflection at the non-reservoir top AVO abnormal display or display is very weak. The AVO inversion based on seismic data further confirms the law that the amplitude of seismic reflection at the top of Shannon sandstone reservoir in the area changes with the variation of offset. This rule has a clear guiding significance for applying the AVO method to reservoir prediction using seismic data. AVO technology solves the problem that can not be solved by the conventional two-dimensional model, exerts the technical advantages of AVO, and has practicality and credibility in searching for oil and gas reservoirs.
