| 摘 要： | 以干扰严重的某工作区为例,探讨高压线对CSAMT法所测数据的影响,总结了本工作区高压线对CSAMT数据影响的特征;根据其电磁干扰特征,寻求数据处理的方法,运用插值法恢复接近正常场的磁信号,再利用原始电场信号和恢复的磁信号,计算得出视电阻率。这种方法经对比和钻探验证,效果良好。

| Abstract: | With the effect of high-voltage line on CSAMT data in a prospecting area as an example, the authors tried to find the meth- ods of data processing on the basis of the characteristics of electromagnetic interference. This paper summarizes the characteristics of the effects of high voltage line on CSAMT data in the prospecting area. The authors recovered magnetic signal close to the normal field using interpolation method, then calculated the apparent resistivity using the original electric signal and recovered magnetic signal. Compara- tive studies and drilling verification demonstrate that this method is pretty good and could be used in data processing under similar con- ditions. |
