摘　　要：聚合物驱是以聚合物水溶液为驱油剂的一种三次采油技术。主要针对特高含水期飞雁滩油田开展了含水较低时(转注聚前综合含水86.1%)的聚合物驱矿场试验。设计注入总量470PV·m/L,主段塞浓度1800.mg/L,年注入速度0.07PV。聚合物驱后地层流动系数大幅度降低,吸水剖面改善,波及体积扩大,综合含水降低14.5%,日产油增加255t,累积增油46×104t,提高采收率3.9%。飞雁滩油田在高含水后期实施聚合物驱取得了很好的降水增油效果。Polymer flooding is a kind of third oil producing technique that the flooding agency is polymer solution, it's chiefly applied in the high water cut oil field. Polymer flooding feild experiment at lower water cut stage was carried out in 2000/11. in feiyantan oilfield (synthetic water cut was 86.1% before experiment). Designed total injection is 470PV. mg/l, density in main jam segment is 1800mg/l, injection speed is 0.07PV/year. Strata flood coefficient reduces dramatically , absorbing water section is well improved , affected volume is enlarged and synthetic water cut reduces at 14. 5%. daily oil production increases 255t/d, total increased oil production is 46×104 t and recovery is enhanced 3. 9%. the perfect result of lower water cut and higher oil production is obtained in polymer flooding experiment at later stage of high water cut in feiyantan oilfield.
