由福建地区各地层测井三侧向电阻率值的统计结果发现，童子岩组低阻特性突出，但有时也会表现出中高阻异常；盖层不同，童子岩组对应的CSAMT法视电阻率曲线类型也各不相同，但谷值都在100Ω·m内；从卡尼亚电阻率剖面图看，童子岩组煤系一般表现为200Ω·m内的低阻异常，当厚度大且含煤性好时，表现为阻值在50Ω·m内的较大面积的低阻异常。总结本地区利用卡尼亚电阻率剖面识别和划分童子岩组地层的经验，认为在中高阻地层中如花岗岩、溪口组等，解释童子岩组煤系的阈值为200Ω·m；而在低阻地层中如沙县组、文宾山组等，可将阈值定为50Ω·m。

The statistics of laterolog 3 resistivity values from various strata in Fujian have found that the low resistivity character of the Tongziyan Formation is prominent, but in rare cases will be medium to high resistivity anomalies. Under different overburdens, Tongzi?yan Formation corresponded CSAMT method apparent resistivity curve types are also different, but all valley values within 100 m. From Cagniard resistivity sections, Tongziyan Formation coal measures strata generally have low resistivity anomaly within 200 m, when thickness is larger with good coal-bearing property will present larger low resistivity anomaly within 50 m. Experiences summed up from using Cagniard resistivity section to identify Tongziyan Formation strata and zoning, considered that the threshold to interpret Tongziyan Formation coal measures strata in medium to high resistivity strata such as granite, Xikou Formation etc. is 200 m, while in low resistivity strata such as Shaxian, Wenbishan formations, the threshold can be 50 m.
