摘　　要：针对文东油田高温高盐油藏堵水难题 ,研制了以阳离子聚丙烯酰胺为主剂的凝胶型堵剂和以热固性树脂和无机充填增强剂为主剂的颗粒型堵剂。通过环境因素对堵剂性能的影响 ,认为堵剂在高温高盐条件下具有强度高、热稳定性好、有效期长等优点 。To solve the water-plugging problem of wendong reservoir with high temperature and high salinity,two kinds of plugging agents are developed.One is a gelling-type plugging agent which mainly consists of the cationic polyacrylamide,and the other is a particle plugging agent which is a mixture of thermosetting resin and inorganic packing reinforced agent.The plugging agents have advantages of high strength,good thermal stability and long valid period on the conditions of high temperature and high salinity.After utilized in production,they have greatly increased the oil production and decreased the water production.In this paper,their performance and influence factors are evaluated comprehensively.
