摘　　要：在分析低电阻率油层产生原因的基础上，给出了低电阻率界限的定式：即小于水层电阻车的4倍作为低电阻率油层的判据。在此基础上通过对低电阻率油层的产能特征的研究认为：因导电矿物引起的低电阻率油层的产能与正常电阻车油层相近，而因物性差所引起的低电阻率油层的产能则低于正常电阻率油层。据此，提出了低电阻率油层低电阻率起因的产能识别方法。This paper established a criterion to judge the foot of highly conductive payzone on the basis of a study on its origin, which is 4-fold resistivity of adjacent aquifer. Furthermore, its delivelability behavior was studied. The results showed that the conductive-mineral-rich payzones have a similar deliverability to normal payzones, while payzones with poor petrophysical properties have lower deliverability than nounal payzones. Then the deliverability recognition method for highly conductive payzones was presented.
