摘要
依据油、气、水混合物电导率主要取决于水的体积含量（持水率）这一性质，并参照固态非均匀介质电阻车分布模型，提出了油（气）、水混合流体电导率与持水率的关系式；探讨了在中等工作频率下用双线圈系测量多相流动持水率的可行性及仪器设计中削弱直耦信号和套管涡流影响的技术措施。
According to the characteristic that the electric conductivity of oil. gas and watermixture depends on water volume fraction. and based on electric conductivity distribution model ofsolid medium, a relationship of multiphase mixture electric conductivity is presented. and thefeasibility of using double-coil with mediate work frequency to measure water holdup of multiphaseavow is inquired. Finally. several questions which should benoticed for instrument designer are poinded out in this paper.
