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。 Based on the analysis of the causes of low resistivity reservoirs, the formula of low resistivity boundary is given: that is, less than 4 times of that of aquifer resistivity cartridges as a criterion for low resistivity reservoirs. On this basis, through the research on the productivity characteristics of low resistivity oil layers, it is concluded that the productivity of low resistivity oil layers due to conductive minerals is similar to that of normal resistance car reservoirs, and the productivity of low resistivity oil reservoirs due to poor physical properties is low Normal resistivity reservoir. Accordingly, a method to identify the low-resistivity causes of low resistivity oil production capacity is proposed.
