摘要
为了解决大地对地震信号(尤其是高频信号)吸收衰减严重的问题,采用介质内测点的方法进行表层结构调查。通过井深和药量的大量试验,最后采用了小药量组合激发的方法;保证高频地震信号能量充分向下传播,从而达到提高地震资料分辨率的目的。实际应用表明,利用该方法收到了较好的效果。
In order to solve the problem that the earth seriously absorbs and attenuates the seismic signal,especially high frequency signal,the article takes the method that double-hole micro-logging to investigate the structure of ground surface.After many tests of well depth and explosion consumption, we finally adopt the less charge shot array to ensure the high frequency energy of seismic signal propagating sufficiently downward,so we can increase the resolution of seismic explosion.This method has been practically approved to acquire better result.
