【摘要】 对广角反射的基本原理作了较为深入的研究 ,同时通过典型模型实例 ,采用高斯射线正演的分析方法 ,得到了一些重要的结论 :采用广角反射可以得到信噪比比常规方法高的地震信息 ,这对地震数据的处理十分有用 ;广角反射波信息出现在直达波以外 ,炮检距很大 ,但能量比非广角反射波能量高。对于深层高陡构造的地质体来说 ,采用常规方法一般不能得到深层高陡地质界面的反射信息 ,这时采用广角反射来采集数据特别实用更多还原

【Abstract】 This paper focuses attention on studying the basic theory of wide angle reflection and analyzing some typical models by using Gauss Ray forward extrapolation, by which people can draw some important conclusions . People can receive higher signal to noise ratio seismic data by using wide angle reflection; The wave of wide angle reflection usually appears outside the direct wave, and the shot offset is very large, but the wide angle reflection wave energy is higher; The method of wide angle reflection is applied to the complex construction , especially to the very steep bed construction when the seismic data are collected.更多还原
