地电阻率井下观测装置抗干扰能力实验研究

experimental research of anti-jamming capacity of geo-resistivity observation equipment in deep borehole

开展地电阻率深井观测系统对地面已知干扰源的抗干扰能力测试,对测试结果进行量化研究,分析地表电磁干扰对地电深井观测的影响程度,期望为将来地电深井方法的研究提供帮助。

As urbanization, industrialization and modernization constantly increasing, the noise source is increasingly higher, especially in the industrial cities. To minimize the noise of the geo-resistivity observation, deep borehole geo-resistivity observation is adapted to reduce the electromagnetic interference. In order to test its anti-interference ability properties, an ex- periment of geo-resistivity observation in deep borehole was carried out under the organiza- tion of Earthquake Administration of Hebei Province.
