摘要
从电场的微分方程出发,得出了混合物电导率的两个公式:1.关于导体和导体形成的混合物的电导率公式;2.关于导体和绝缘体形成的混合物的电导率公式。将这两个公式应用于测井解释,对解释泥质砂岩的双水模型作了有效的改进。
In this paper,we obtain two conductivity formulas for mixture.First formula is for mixture of conductors.Second formula is for mixture of conductor and insulator.Based upon above conductivity formulas,we obtain a new function for the logging interpretation of shaly sands [sq.(29)].The data of experiment for shaly sands have computed with new function.The results show that the accuracy of the new function is higher than the 'dual water' model function.
