The present stage common method is utilize electric conduction nature and dielectric characteristic difference to recognize fluids, for example conductance method, electric capacity law and so on.
现阶段运用最多的是利用油气与水的导电性质和介电特性的差异识别井内流体的方法，例如电导法，电容法等。
In high frequency, it also have conductance at dielectric material due to dissipation factor of the dielectric material causing the current leakage.
介质电导的存在，是由于介质的耗散因子的存在，使得再高频下，传输线存在漏电流。
