摘　　要：针对延长油田低孔低渗、地层水矿化度高、采收率低的的问题,研究应用了生物活性剂驱油技术,介绍了该技术的驱油机理,通过洗油能力、界面张力、耐盐性、抗钙镁、驱油评价等一系列性能测试,评选出了适合延长油田可大幅度提高驱油效率的驱油剂配方,并在现场应用取得了较好的增产效果。Yanchang oilfield is characterized by low-porositylow-permeability,high formation water salinity and low recovery ratio,in view of these problems the application research of biological active oil displacement agent has been carried out,which introduces the technology of oil displacement mechanism.Through a series of performance test on the washing capacity,interfacial tension,salt resistance,resistance to calcium and magnesium,the displacement efficiency of oil displacement agent formula has been evaluated and selected,and the field application has achieved good production effect.
