折射波法是一种有效的地震勘探方法,在工程地质、水文地质、油气勘探及探查地球深部构造等方面有重要应用。本文在折射波正演模拟方面采用射径法和逐段迭代射线追踪法进行折射波正演模拟,采用射径法进行了针对多层倾斜界面的折射波运动学反演模拟。数值模拟计算速度快,反演精度高。
Refraction wave method is an effective seismic exploration method, which has important applications in engineering geology, hydrogeology, oil and gas exploration and exploration of the deep structure of the earth. In this paper, we use the radial method and the paragraph-by-section iterative ray tracing method to conduct the refraction wave forward modeling in the forward modeling of refracted waves, and the refraction wave kinematics inversion simulation for the multi-layer oblique interface is conducted by using the radial method. The numerical simulation is fast and the inversion precision is high.
