摘要
针对杏南开发区聚合物试验区所反映的杏二水源二价钙、镁离子矿化度高,对聚合物溶液粘度影响较大,筛选了两种抗盐聚合物采用污水配制,从粘浓度、流变性、提高采收率等方面进行了室内评价,并开展了污水配制抗盐聚合物现场试注,为大规模推广应用做了前期准备工作。
The problem of polymer flooding test area in Xingnan development area is high salinity of divalent calcium and magnesium ions in Xing 2 water source having effect on the viscosity of polymer solution. This paper screens two kinds of polymer to prepare with produced water. It performs lab evaluation on concentration and viscosity, rheology and enhanced recovery, and performs a pilot test preparing for popularized LE work.
