摘　　要：常温条件下聚合物反相乳液调驱剂是油包水的稳定乳液,根据孤岛油藏特点对该调驱剂进行了适应性室内评价,模拟地层条件下转相成胶时间大于3d,单管岩心封堵试验的阻力系数为10.4,三管模拟注聚后调驱试验最终提高采收率13%,说明该体系可以到达岩心深部发挥调驱作用。在6个井组实施了反相乳液调驱体系调驱后,注水井油压平均上升了1.8MPa,对应油井见效期内含水平均下降了3.4%,平均单井增产原油377t。Under the condition of ambient temperature, inverse polymer emulsion was a stable water-in-oil emulsion. According to the reservoir characteristics in Gudao Oilfield, the adaptability of profile control agent was evaluated in laboratory, the phase transform and gelling time of simulated strata were more than 3d, the drag coefficient from single core plugging test was 10.4, after 3 string polymer flooding, the ultimate recovery percent was 13%. It indicates that the deep profile control can be effective by using the polymer system. After it is used in 6 wells, oil pressure goes up 1.8MPa in average in water injection wells, water cut reduces 3.4% in response wells within the validate period, single well oil increases 377t in average.
