摘　　要：合成了驱油用接枝型聚丙烯酰胺聚合物,在合成该聚合物时引入了一种自主合成的活性单体。研究表明,该聚合物与原油之间的界面张力能达到10-2数量级,在满足驱油的同时又能达到洗油的目的。对聚合物与原油之间的界面剪切粘度研究表明,随剪切速率的增加,新型聚合物的界面剪切粘度不降低(无剪切变稀特性),也不增加(无剪切增稠特性),有利于产出液的破乳。A novel polymer for EOR was synthesized which was graft polyacrylamide, an active monomer was inserted into the polymer,which was synthesized independently. The results showed that the interfaeial tension between polymer and simulative oil could reach the level of 10^-2 order of magnitude. It could satisfy the requirements of oil displacement and oil washing simultaneously. Interfacial shear viscosity between polymer and simulative oil was investigated. With the increase of shear rate, the interfacial shear viscosity remained stationary. It showed that polymer did not have shear thinned behavior and shear thickened behavior. It was profitable to demulsification of production fluid.
