摘　　要：各种化学堵水剂特性差异较大,选择性堵水技术及堵剂一直是研究重点。介绍的水凝树脂具有油、水选择性反应和凝固体在孔隙中对油、水相渗影响差异较大的特点。通过对水凝树脂的室内评价和现场试验分析,认为该树脂可以应用于油井多层合采或大厚层笼统堵水工艺措施,在纵向挖潜具有一定选择性封堵效果。The characteristics of all kinds of water plugging agents are different.The main researches are selective water plugging technology and selective water plugging agents.The characteristics of hydrogel resin were presented,it could react with oil and water selectively and had greater influence on oil-water relative permeability.By the on-site experimental analysis and laboratory evaluation of hydrogel resin,it is known that the resin could be applied for multiple-zone commingled production or general water plugging technique in big-thick-stratum reservoirs,and had selective plugging effect.
