空间电磁干扰及检波器电气组合方式的抑制作用

Suppress space electromagnetic interference by geophone array.

在高精度地震勘探中,对影响地震勘探资料质量的主要干扰源进行研究分析,采取有效措施克服或减轻干扰,具有重要意义。本文简述了空间电磁感应和干扰的一般原理,从理论分析和实验结果两方面论述和证明了:检波器电气组合方式不同,抑制空间电磁干扰的程度亦不同。在工业发达地区和空间电磁干扰严重地区,适合使用串并结合的检波器串施工。

In order to make sure seismic data quality for high-resolution seismic exploration, it is necessary to make an analysis on main interference and take effect measures to weaken or eliminate them. This paper describes space electromagnetic induction and interference in brief. Furthermore, the theoretic analysis and experiment results proved that different geophone array has different suppressing effect for space electromagnetic interference. It's better use the mode of series-parallel geophone group in industrial areas or areas under heavy interference.
