摘　　要：为了提高聚合物驱后注水开发效果,研制了一种由聚氧丙烯双烷基酚硫酸盐和聚氧乙烯烷基醇醚丙撑磺酸盐类表面活性剂驱油体系。概述该复合驱油体系的配方、性能、吸附改进剂的影响,以及提高采收率能力评价。其性能评价结果表明,在60℃条件下,复配的表面活性剂对飞雁滩油田的原油有较好的适应性。在深部液流转向调剖后,注入驱油体系,可较大幅度提高采收率。To improve the development effect with water injection after polymer flooding in Feiyantan oilfield, the paper studies a surfactant system containing two-alkyl polyoxypropylene ether sulfate and alkyl polyoxyethylene ether propylene sulphonate. In this paper, it introduces the formulation and performance of the polymer oil flooding system, the effect of adsorption improver and ability evaluation to improve recovery. The results suggest that the compounded surfactant has good adaptability to the crude oil of Feiyantan Oilfield at 60℃. The oil recovery can be greatly improved by this formulation when it is injected after the deep fluid turns profile modification.
