摘要： 为了探究强碱三元复合驱后进一步提高采收率的措施,以大庆杏树岗油田为实验平台,以采收率、含
水率和注入压力为评价指标,在恒速和恒压条件下开展了强碱三元复合驱后进一步提高采收率方法增油效果实验
研究。结果表明,强碱三元复合驱后注入高浓度聚合物溶液、无碱二元复合体系和弱碱三元复合体系都可以进一步
提高采收率,其中高浓度聚合物驱增油效果较好。后续注入压力升高幅度愈大,采收率增幅愈大。考虑到大庆油田
储层以及设备耐压能力的制约,结合经济技术效果的综合评价,无碱二元体系更具有应用前景。

关键词: 高浓度聚合物, 弱碱三元, 无碱二元, 增油效果, 物理模拟, 注入压力

Abstract: In order to explore a method of further enhancing oil recovery after alkaline/surfactant/polymer flooding, taking Xingshugang oilfield in Daqing as an experiment platform and regarding oil recovery, water content and injection pressure as evaluation indicators on enhancing oil recovery, an experiment was conducted under the condition of the constant temperature and constant pressure. The results showed that alkali/surfactant/polymer with strong base system, surfactant polymer system and alkali/surfactant/polymer with weak base system could all further enhance oil recovery, and the effect of high concentration polymer liquor was the best. The greater the subsequent of the injection pressure rose, the more the recovery growth was. Taking into account the constraints of Daqing oilfield reservoir and equipment capacity. Based on the comprehensive consideration of technical and economic effects, aurfactant polymer system has more application prospects.

Key words: High concentration polymer, Alkalescent alkaline/surfactant/polymer system, Surfactant polymer system, Effect of increasing oil, Physical simulation, Injection pressure
