庐枞矿集区地震资料干扰波分析与压制研究

Analysis of seismic data interference wave and suppression research in Luzong Mining Area

庐枞矿集区地表条件及地质构造非常复杂,导致地震资料波场关系复杂,有效反射信号弱,干扰波种类多及特征在时间与空间方向上差异大。通过对干扰波特征及压制技术的分析研究,确定了适合矿集区复杂地表条件下的干扰波压制方法和流程。庐枞矿集区地震资料处理的实际应用显示,使用该方法压制干扰波效果明显,提高了资料的信噪比。

The surface conditions and geological structure of Luzong Mine area are very complex,which leads to the complex relationship of seismic data wave field,weak effective reflection signal,many kinds of interference waves and great differences in time and space.Based on the analysis of the characteristics of the interference wave and the suppression technique,the method and flow of the interference wave pressure under the complex surface conditions in the ore collection area were determined.The practical application of seismic data processing in Luzong Mine Area showed that the method has obvious effect on suppressing interference waves and improving the signal-to-noise ratio of the data.
