摘要
为改善陆相砂岩油田正韵津厚油层特高含水期的驱油效果，大庆油田在中区开展了聚合物驱油现场先导性试验，本文主要介绍试验区的基本情况，试验目的层的物性及待高含水期后的剩余油分布，并着重阐述进行聚合物驱后油水井的动态反应，供进一步研究聚合物驱油机理和扩大注入规模时借鉴。
In order to improve the flooding effect in thick continental sandstone reservoirs with positive rhythmic sedimentation at the later high water cut stage,a pilot test of polymerflooding is made in the central area of Daqing Oilfield.In this paper,the purpose of the test,the petrophysical properties of the reservoir and the distribution of the remaining oil in-placeat the later high water cut stage are introduced,and the performance of the producers and theinjectors after polyrner flooding is emphatically described,so as to provide reference for further mechanism study and large-scale application of polymer flooding.
