摘要
多分量地震资料解释的首要问题就是多分量的标定和对比,其中最关键的是转换波反射系数的求取及子波的选取,然而Zoeppritz方程在数学表达上极其复杂,在物理意义上也不直观,因此很难得到直接的应用。为此,在详细介绍五种近似公式的基础上,利用六种模型分析了随入射角的变化各公式的适应性,最后得出结论,Aki和Richard的近似公式适应性普遍比较好。
The most important problem in interpreting muhi-wave seismic data is multi-wave calibration and contrast, in which the ex- traction of the reflection coefficient and the selection of the wavelet are most critical. However, Zoeppritz equation is extremely complex and does not have intuitive physical meaning, and hence it is difficult for this equation to receive a direct application. This paper there- fore makes a detailed description of five approximate formulae, based on analyzing the suitability of six models with the variation of the angle of incidence. It is concluded that the approximate formula Aki＆Richard generally has better adaptability.
