摘要
本文根据宝鸡深井地电阻率观测系统的观测方式,结合台站电测深数据建立有限元模型,对于井下地电阻率面临的典型干扰:浅层介质变化和地表电流干扰进行有限元模拟。计算得到了宝鸡深井地电阻率受浅层介质变化和地表电流干扰的影响程度。本文章的研究成果对于深井地电阻率的系统设计建设,干扰异常分析有重要参考意义。
The finite element model of Baoji deep geoelectrical resistivity observation is established according to the observation way and sounding data. It simulates the finite element method for typical interferences, the change of shallow medium and the surface current. It calculates the influence degree of Baoji deep geoelectrical resistivity observation from the change of shallow medium and the surface current. The research results of this article have important reference for the design and construction of the deep geoelectrical resistivity observation system and the analysis of the disturbance.
