摘　　要：草舍油田泰州组油藏的开发经历了弹性驱动、水驱、CO_2混相驱等三个阶段,在水驱、CO_2混相驱后,储层流体进一步复杂化,采用常规测井方法难以对剩余油饱和度进行准确的定量计算。通过开展高精度碳氧比测井能在套管中对储层水淹程度、剩余油饱和度等作可靠的评价,从而为后期测试选层提供重要的依据。The development of Taizhou formation reservoir in Caoshe oilfield has undergone three phases： elastic drive, water drive and CO2 miscible drive. Further complicated reservoir fluid makes the quantitative interpretation of remaining oil saturation harder to achieve by conventional logging method only. The carbon-oxygen spectral logging makes it possible to achieve the reliable evalu- ation of reservoir flooding degree and remaining oil saturation in casing, thereby providing important references for follow-up test layer selection.
