在用射线追踪模拟法再现潜在油气藏的AVO响应时,常常忽略局部转换横波。在做一次波射线追踪模拟时常用Zoeppritz方程描述反射波振幅。然而,局部转换横波常常对地震响应产生一阶影响。人们对这种现象并没有充分地认识,或对其意义未能了解清楚。只包含一次波的Zoeppritz模拟法很可能导出不正确的结果。转换波与来自地层底部的一次反射波间的干扰将随着地 When ray tracing simulations are used to reproduce the AVO response of potential reservoirs, the local transition shear waves are often overlooked. In a wave-ray tracking simulation Zoeppritz equation is often used to describe the reflected wave amplitude. However, the locally converted shear waves often have a first order impact on the seismic response. People do not fully understand this phenomenon or fail to understand its meaning clearly. The Zoeppritz simulation, which contains only the first wave, is likely to lead to incorrect results. Interference between the converted wave and a reflected wave from the bottom of the formation will follow the ground
