| 摘 要： | 由于地震波在到达检波器时的传播方向与检波器接收方向存在夹角,尤其是在浅层和大偏移距的情况下,它会影响接收到的反射波的振幅.本文利用Shuey近似方程建立模型,对出射角和振幅的关系进行定量分析,通过研究表明,由于出射角而导致的振幅变化会影响到AVO分析的结果.因此,为了满足地震属性分析的需要,提高分析的精度和结果的准确性,在地震数据保幅处理过程中,有必要对地震信号进行径向补偿.

| Abstract: | Because there exists an angle between propagation path of seismic wave and receive path of geophone,it will affect echo amplitude,especially in the situation of shallow layer and large offset distance.This article have a quantitative analysis of emergence angle and amplitude by using a model of Shuey approximate equation.The effect caused by emergence angle would be damaging to the results of the AVO analysis.In order to meet the demand of the precision of seismic attribute analysis and improve the accuracy of results.It's necessary that we should compensate the radial loss in the preserved amplitude processing. |
