摘　　要：根据台兴油田阜宁组三段储层油藏特征和开发现状,利用长岩心驱替实验装置,对长岩心注二氧化碳驱油进行了室内模拟实验,得到了阜三段油藏流体在水驱后三个注CO2气驱压力点下的采收率和相态变化的重要参数,为下一步确立台兴油田合理开发方案提供了依据。In this study,according to reservoir characteristics of Fulin 3 Member and their development status quo,a simulation experiment that injects CO2 into long core for oil displacement is conducted using long core's displacement unit.Two important parameters of reservoir fluid recovery and phase-behavior change,at three pressure points of CO2 injection displacement after water displacement,are obtained.The studied result provides a basis for establishing next reasonable development scheme of Taixing oilfield.
