深井电极交叉供电对自然电位的影响
The effects of cross-power supply of the electrodes on spontaneous potential in deep wells
摘要
Abstract
At first, through the experimental demonstration, the reason of the spontaneous potential distortion in the Pingliang deep well resistivity observation is caused by the cross-power supply of the electrodes. Secondly, the effects of different electrodes powered on spontaneous potential were discussed. The results show that the power supply on measure electrodes will affect the spontaneous potential, but will not affect the resistivity measurement; The effects of unipolar electrode powered on spontaneous potentials are step jump, and recovers exponentially. The recovery time is of 10 hours or so. The peak of interference related to the supply current, power supply time and so on; Finally, The correction of the observed data has achieved good results.关键词
