摘　　要：油藏开发中后期,通过测井获取的井眼附近的剩余油饱和度是制定措施的重要依据,也是描述平面剩余油动态变化的基础。通过调研国内外剩余油饱和度测井相关文献,从测井仪器的原理、硬件组成进行梳理,对常见剩余油测井方法进行了总结。综合考虑安全、环保和获取的信息,得出过套管电阻率方法和脉冲中子源测井方法具有绿色环保的优点,施工便捷,且获取信息丰富,为解释挖掘地质信息提供了数据支撑,是本领域未来的发展主流趋势。In the middle and late stage of reservoir development,the remaining oil saturation near the wellbore obtained by logging is not only an important basis for formulating measures,but also the basis for describing the dynamic change of plane remaining oil.This paper investigates a large number of domestic and foreign residual oil saturation logging documents,and summarizes the residual oil logging methods from the principle and hardware composition of the instrument.Considering the safety,environmental protection and the obtained results,it is concluded that the through casing resistivity method has its value.Pulse neutron source logging methods have some advantages:environmental protection,convenient construction and rich information.It provides data support for interpreting and mining geological information and is the mainstream of future development in this field.
