摘要
为研究胜利油田三次采油后期(包括注聚、注胶)提高采收率的接替技术,拓宽三次采油研究领域,开展了高效驱油体系的研制工作。针对胜利油田的油水特点,筛选出多种表面活性剂试样及其复配体系进行油水界面张力测定,成功研制出具有良好驱油性能的复合驱配方。室内物理模拟试验结果显示,这种驱油体系可在水驱基础上提高采收率19％。
According to the characteristic of oil and stratum water in Shengli Oilfield, several surfactants and their composition systems were screened and the interfacial tensions between the crude oil of Shengtuo Oilfield and the surfactant systems were measured. A high - performance and low - cost oil - displacing system was successfully developed. The simulation experimental results showed that the oil recovery could be increased 19% on the foundation of water - displacing.
