P-SV波反射系数计算方法综述

Review of computational methods for P-SV wave reflection coefficients

对P-SV波反射系数计算方法的研究,不同学者从不同的角度给出了不同的简化或近似公式。总结了20余种P-SV波的反射系数计算方法,并对2界面Ostrander模型的反射系数进行了试算,结果表明,在小角度入射角情况下,这些方程都能较好地吻合Zoeppritz方程解。最后指出了计算P-SV波反射系数方法的发展方向。

Many different simplified or approximate formulas have been proposed for calculation of P-SV wave reflection coefficients.More than twenty formulations of P-SV wave reflection coefficients are discussed in this paper.Results from 3-layer Ostrander model show that the values from these equations are very close to that from Zoeppritz equation for small incidence angles.The development trend for computing P-SV wave reflection coefficients was also discussed.
