三水导电模型系基于岩石的导电路径是由自由流体水、微孔隙水和粘土束缚水并联而成的理论。利用其对塔北地区的部分低阻储层进行了解释。与传统的导电模型相比，新的三水导电模型极大地改善了测井识别低阻油气层的能力，提高了含水饱和度的计算精度。该模型不但适合于通常的砂泥岩地层电阻率解释并且能很好地描述低阻储层的电性特征。

The three-water(TW) conduction model bases on the theory whoseconductive path is paralleled by free water, micro-porous water and clay bound water.It was applied to the interpretation of low resistivity reservoir in the northern area of Tarim basin.Compared with traditional conduction models the new TW conduction model greatly improved the ability of well log to identify the low resistivity hydrocarbon reservoir and gave more precision to the water saturation estimation. This model can be not only applicable to resistivity interpretation of general shaly sand stone strata but also well description of the electrictity character of low resistivity reservoirs.
