折射波法探测断层的实例分析
|
摘要
折射波法探测断层的实际工作中,不仅能观察到上、下盘的正常折射波及棱上绕射波,而且还可以看到因绕射、透过所产生的一些次生异常波(折绕射波、绕折射波),这些波在记录上出现,并构成一幅复杂的波形记录图。如何在野外探测中区分识别这些波形在折射波原始记录图上的特征,成为本文的研究重点;另外,在地震勘探中,有效波和干扰波的利用并无严格的界定,在资料解释过程中可以利用多种波的信息。
In the prospecting of faults by the refraction wave method,not only the ordinary refracted waves from the downthrow and upthrow sides of a fault and the diffracted waves from the fault plane are observed but also certain secondary waves resulted from diffraction and transmission can be recorded on the seismograms.The whole set of waves constitutes a very complicated picture of the seismograms.How to identifying the characteristics of these waveforms on the refraction of the original records from maps in the field detection has become the focus of this study;In addition,in the seismic exploration,the use of effective wave and interference wave is not strictly defined.In the process of data interpretation,you can use a variety of wave information.
