深井地电阻率观测装置构建及其近场干扰测试
Construction of an Earth Resistivity Observation Device in a Deep-well and Its Near-field Interference Test

基于新建成的新疆昌吉深井地电阻率综合观测台站，介绍了台址踏勘和场地测试结果；分析了观测、研究、实验、对比多种需求，依据需求设立了相应的观测分量；讨论了深井观测特有的装置自身一些技术指标的测试功能，给出了接地电阻、线路绝缘测试方法，弥补了当前深井地电阻率观测中的两项现实需求。此外，借助本台站具有的场地条件，完成了近场干扰实验。
In this study, a survey of the newly built deep-well earth resistivity observation station in Changji prefecture, Xinjiang and its site test results are introduced. According to the various requirements of observation, research, experiment, and comparison, corresponding observation components were set. The test function of some technical indexes of specific observation equipment in the deep well is discussed, and a test method for grounding resistance and circuit insulation is presented. Therefore, two realistic requirements of deep-well earth resistivity observation are met. In addition, a near-field source interference experiment was performed using the site conditions of the station.
