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.
