摘要
提出了一种基于光学干涉原理,用地震波代替光波进行地震成像的一种新的成像方法:地震干涉成像方法。用这种方法进行微震定位的特点是不需要进行初至拾取,观测系统也可以使用任意阵列检波器。模拟了一个地下震源的二维时间延迟记录,编制了基于C语言的震源定位程序,对接收的记录使用此方法进行成像。通过程序运行结果验证了此方法的可行性,且定位效果明显。
Based on the optical interferometric principle,a new seismic imaging method which use seismic wave to replace optical wave,named seismic interferometric imaging method is presented.This method needn't to pick up first arrival,and can use any array detectors as the observation system.A two-dimensional time delay record from a subsurface source is simulated,and a C-based positioning procedure for seismic source is established,then use this method to invert.The result of this program indicates that the method is feasible and high in location accuracy.
