三种弹性波阻抗方法的对比分析
omparative analysis on three Elastic Impedance methods
地震反演方法中,常规的叠后波阻抗反演方法建立在地震波垂直入射假设的基础之上,这种方法在地震勘探储层预测中取得了一定的效果。为了更好地指导弹性波阻抗反演技术应用于实际,本文对比分析了弹性波阻抗公式、归一化弹性波阻抗表达式和扩展弹性波阻抗公式在双层流体替代模型中充填水,油和气时的波阻抗响应特征,结果表明不同的公式适用于不同的地质沉积环境。
On the basis of the assumptions of vertical seismic wave incident, the conventional method of Acoustic Impedance gained efficient results in seismic prospecting. To better instructing the practice of elastic impedance inversion technology, this paper is to compare and analyze the different responses of elastic impedance, normalized elastic impedance and extended elastic impedance in the two-layer fluid replace models under the conditions of water, oil, gas and the reflectance under the same fluid model. The results show that different equations can apply to different strata sedimentary environments.
