井下电极观测地电阻率排除地面干扰的实验
ELIMINATION OF SURFACE DISTURBANCES IN EARTH-RESISTIVITY MEASUREMENT BY LOWERING THE ELECTRODES IN SHALLOW WELLS
-
摘要: 本文简单分析了山东省临沂台地电阻率“年变化”干扰的主要原因。着重介绍了该台井下电极观测地电阻率排除地面干扰的实验情况,以及与地面观测对比的结果.Abstract: This paper starts with an analysis of the cause of annual variation of earth-resistivity recorded at the Lin Yi, Shandong Province, earth-resistivity station. Then, the experiment for elimination of surface disturbances in earth-resistivity measurement by lowering the electrodes in shallow drill holes is described and the results compared with that observed on surface.
