| 摘 要： | 针对孤东油田二区Ng4-5矿场注聚井因井底附近聚合物滤积导致注入能力下降的问题，进行了间歇注聚试验并考察了注入压力与注入量、地层启动压力与地层吸水指数的关系。实施间歇注聚之后，截止到2007年12月底，该区累计增加注入量46254m^3，对应油井累计增油8042．5t，增注、增油效果显著。

| Abstract: | The decline of polymer injected capacity resulted from filtered polymers at the well bottom in the workplace of the author.In order to resolve the trouble,the intermittent polymer injected experiment was carried out,the relations between the injection pressure,injection volume,the stratum start-up pressure and stratum water absorbing capacity investigated.The intermittent polymer injected has been brought into operation and the results satisfied,the injection volume and oil increased by 46 254 m3 and 8 042.... |
