摘要
介绍了根据斯奈尔定律和Zoeppritz方程,以动力学射线追踪进行二维各向同性介质多波地震正演模拟的一种方法,该方法不仅适用于复杂的地质构造情况,而且也适用于地层速度纵向和横向变化的情况,不仅可以追踪地震波的射线旅行时,也考虑了地震波在地层界面处的透射和反射损失等因素,从而可追踪地震波的动力学特征,该方法速度快,精度高,是一种比较实用的动力学射线追踪方法。
A method of multiwave seismic forward modeling of 2-D isotropic media with kinetics raytracing, which based on the Snell law and Zoeppritz equations,is introduced in this paper. This method not only can flexibly apply to arbitrary complex geologic structures,but also can apply to the strata of velocity varying with depth or at horizontal direction. And it not only can trace the ray travelling time of seismic waves,but can trace the seismic waves' kinetics properties by considering such factors as reflection loss and transmission loss and so on. Moreover,this method also have the advantagesof fast tracing and high presision,so it is a relatively practical ray-tracing method.
