地下线状长导体对激发极化场的影响——以胶东地区为例

The Influence of Underground Long Linear Conductor to IP Field——Setting Jiaodong Area as an Example

摘要:

线状长导体，如金属管道、裸金属线、光缆等，其直径相对于埋深虽然很小，但受到激发时，能够产生很大的极化场，生产实践中对极化率的影响很大。该文主要研究了中梯和联剖2种装置下地下线状长导体的异常特征，分析了异常产生的原因，并提出了辨别这种干扰因素的方法。

Abstract:

The long Linear conductor, such as metallic pipeline, the bare metallic line, optical cable etc, although their diameter is small to their burying deepness, when it was induced, they are polarized and can produce a big polarization field. In the practice, the influence is very large to the polarizability. The anomaly characteristics of the underground long linear conductor in medium gradient and unite section survey have been studied, the cause of the anomalies have been analyzed, and the method for identifying this kinds of interfere has been pointed out.
