摘　　要：车2井区齐古组油藏,储层粘土矿物含量相对较高,具有强水敏低电阻出油的物点,分析了低阻出油的原因,含油饱和度解释模型引入了变地层水电阻率,油层识别图版引入了Rw/Rt参数,解决了“低阻油层”识别的难题。Car-2 district J3q group oil reservoirs with layers of mineral content that have relatively high clay,have strong-water sensibility and low resistance which produces oil order,and the reason why low-resistance oil reservoir can produce oil is analyzed,at the same time,the degree of saturation of oil explanation models have introduced the resistivity of truning stratum water;oil reservoir identification drawing board introduces Rw/Rt parameter,thus solving the problem that it is hard to identify low-resistance oil reservoir.

关 键 词：强水敏 变地层水电阻率 Rw/Rt参数 低阻油层 识别
