深井地电阻率观测装置构建及其近场干扰测试

摘要

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 Changj i prefecture,Xinj iang 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 equip-ment in the deep well is discussed,and a test method for grounding resistance and circuit insula-tion 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.
