Whitcombe扩展弹性波阻抗公式的改进
Improvement of Whitcombe's extended elastic impedance formula
摘要
Abstract
When elastic impedance is used in practice, it needs to estimate the incidence angle,sin~2 θ(whereθ is the incident angle) may exceed unity because of the existence of errors, which makes elastic impedance inversion extremely unstable. Used substitute for (Whitcombe et al., 2002) derived the extended elastic impedance, improved the stability of elastic impedance inversion. Based on the three term Zoeppritz equation (Aki and Richards, 1980), this article improves Whitcombe's extended elastic impedance. The improved extended elastic impedance increases the computational precision.关键词
