| 中文摘要: |
| 根据井中激电地—井方式所探测矿体的埋深一般都较大的特点,通过增加两个假定条件,即矿体处的作用场近似地看成均匀场并视矿体为均匀极化,极化方向确定为供电点A到极化板体中心连线方向,提出了井中激电电磁类比正演计算方法。模型正演结果与定性分析电场在井轴的分布特征是一致的。应用极化体的正演计算,对内蒙古新巴尔虎右旗某多金属矿区井中激电异常定性解释的正确性进行了判断和定量解释。 |
| 英文摘要: |
| This paper presents a forward calculation method of the borehole induced polarization electromagnetic analogy according to the azimuth measurement characteristics in the ground-well induced polarization by adding two assumptions, namely, the effect of ore field approximation is regarded as uniform field and ore body is uniformly polarized, the polarization direction is determined as the center point of supply A to the polarization plate line. The authors validate the correctness of the qualitative interpretation of the borehole induced polarization anomalies outlined in a multi-metal deposit at Xinbaerhu Youqi in Inner Mongolia by the forward calculation of polarization body and the quantitative interpretation is given. |
