| 摘 要： | 采用Dias模型表征介质的激电效应,对三层水平地层中间层为极化层的天然电磁场源激电测深之视电阻率及阻抗相位进行了理论计算.利用中间层充电率m2≠0和m2=0时相同频率的视电阻率振幅比和阻抗相位差作为提取激电效应的参数,重点讨论了不同电阻率断面类型对激电测深异常的影响.最后,给出了在一个已知铅锌矿上的试验结果. |

| Abstract: | Take the Dias model expression IP effect of medium,In the case of a horizontal three-layer that middle layer is polarized. Fist calculate the apparent resistivity and impedance phase under natural electromagnetic source, Then extracte the IP parameter of amplitude ratio and phase difference from the data that frequency is same but chargeability is differ (m2≠0, m2=0), discussed the influence for IP sounding anomaly when the diffen section of resistivity. The last supply a test result over the lead zine mineral deposit. |
| Keywords: | Dias model polarizatal horizonpal-layer Netural electromegnetic source Induced Polarization Sounding |
