摘要： 表层模型层析反演技术,是利用地震记录初至波的时间,运用射线追踪方法反演地表及近地表不同介质的速度模型,以获得地震观测点处地表及近地表的速度和深度信息,建立相应的表层结构模型,在此基础上分别求取激发点和接收点的静校正值,从而消除静校正影响,提高地震反射波的分辨率,最终得到高质量的地震剖面。

Abstract: The tomographic inverse technique for near-surface model is a model to be used for inversing various media velocity from subsurface and near-surface by means of seismic first arrival time and seismic ray-tracing method in order to obtain subsurface seismic velocity and corresponding depth information at geophone spots as required and develop corresponding surface structural models. According to these, we can get static correction values of shot point and acceptance point so that eliminates influence from static corrections and improve resolution of seismic reflecting wave for gaining high quality of seismic profiles.

Key words: first arrival, tomographic inverse, static correction, seismic ray tracing, bow tie
