摘要
本文试图从两个方面提高波动方程偏移的效果:1.使用全方向波动方程进行偏移,使之适用于任意倾角界面的反射;2.使用有限元素法提高微分方程数值解法的精度。
This paper attempts to improve the efficiency of wave equation migration in two ways,the first is using all-direction wave equation in migration in order to suit reflections of interfaces with any dips; the second is emplogying finite element method to improve the accuracy of digital solution of wave equation.
