国外碱-表面活性剂-聚合物三元复合驱研究进展

Research Progress on Alkali-surfactant-polymer Triple Flooding in Foreign Countries

介绍了2000-2018年委内瑞拉、加拿大等有大中型油藏国家针对碱-表面活性剂-聚合物(ASP)驱作为油田提高采收率储备技术的实际情况;在介绍ASP驱配方案例的基础上总结了实验结论,特别深入介绍了液氨、有机碱、阿拉伯胶等在ASP驱中的应用研究情况;在ASP驱面临的困境方面介绍了液氨和有机碱减小储层伤害的优势以及ASP体系粉末化和研发ASP驱用新型化学品的策略;提出了在超低界面张力成像设备研究上加快应用"3D+新公式"技术精准测试等具体建议。

The actual situation of reserve technology for alkali-surfactant-polymer （ASP ） flooding in oilfields in large and medium-sized reservoir countries, including Venezuela and Canada in 2000-2018, was introduced. The conclusions of the experiments were summarized, and the application of liquid ammonia, organic bases, gum Arabic and other chemicals in ASP flooding were particularly introduced in depth. In terms of the difficulties faced by ASP flooding, advantages of using liquid ammonia and organic bases to reduce reservoir damage and strategies for powdering ASPs and developing ASPs to drive new chemicals were introduced. Specific recommendations for accelerating the use of “3D＋new formula” technology for accurate testing on ultra-low IFT imaging equipment were proposed.
