我们已经研究了将环境微震能量用作微地震能源——一种不寻常的无震源地震勘探法。该方法包括将检波器组对环境声能响应的比较长的记录进行预处理和相关。最终的相关记录可以作为一般的地震资料进行处理,迭加,滤波和显示。在理论上进行了说明并实验地用简单的电模拟论证了在地面反射系数为1时,垂直向上传播的波产生的记录白相关的一边相当于地面上向下传播的平面波源的反射响应。为了评价在工作环境下这
We have studied the use of ambient microseismic energy as a source of microseismic energy - an unusual sourceless seismic exploration method. The method includes preprocessing and correlating the geophone group to a relatively long recording of the ambient sound response. The final related records can be processed as general seismic data, superimposed, filtered and displayed. It has been theoretically demonstrated and experimentally demonstrated by simple electrical simulation that when the ground reflection coefficient is 1, the vertical correlation of the recording white produced by the vertically upward wave corresponds to the reflection response of the planar wave source propagating downwardly on the ground. In order to evaluate this in a working environment
