摘　　要：水驱油岩石物理实验可以近似模拟储层水淹过程,但不能逐一分析岩心电阻率变化的影响因素。本文利用多倍数物质平衡方法模拟水驱油岩心电阻率实验,并分别讨论各项地层因素的影响。结果表明,随注入水量的增加,岩心电阻率先降低后升高。数值模拟与岩心实测具有较高的匹配度,能够精确描述各参数水淹过程中对地层电阻率的影响。The water-displacing-oil rock physics experiment can simulate the water flooding process,however,is inflexible in describing the changing tendency of rock resistivity caused by various factors.We adopt a multiple-ratio material balance method to numerically simulate water-driving-oil.With increase of injected water,the rock resistivity first decreases and subsequently increases. The results show that the numerical simulated results agree with the physical experiment very well,and accurately describe the impact of the parameters on formation during water-driving-oil.
