Abstract: The remaining oil saturation evaluation of water drive oilfield using logging technique in high-water injection stage is a challenge for finding the remaining oil.The experiments and analysis on logging methods were carried out in laboratory.The effects of the resistivity of mixed fluids and the shale content on well logging were analyzed according to the responses of the properties of injected water and reservoir to logs.The combination logging method of polarization(IP) and spontaneous potential(SP) was induced.A chlorine spectral logging method was selected.The two methods applied to the development of water-flooding formations in water drive oilfields.Asatisfactory effectiveness has been achieved.

Key words: water injection oilfield, logging method, remaining oil saturation, potential logging, chlorine spectral logging

摘要： 水驱开发油田的饱和度测井是在高含水期开发油田寻找剩余油的一种重要手段.为此,在室内进行了实验研究和方法分析,根据注入水及储层性质对测井特征的响应,重点解决了地层水电阻率、泥质的影响问题.采用激发极化与自然电位组合的测井方法和氯能谱测井方法进行了饱和度测井评价,并在水驱开发油田水淹层测井中进行了应用,取得令人满意的效果.
