摘　　要：收集了大庆油田北一区断西聚合物驱工业试验区采出水，用于配制聚合物溶液并在非均质人造油层物理模型上进行了驱油试验。Stryrene/maleic anhydride/acrylic acid ester (C 18 and C 18-24 ) terpolymers SMAE 18 and SMAE 18-24 are treated in toluene solutions by aliphatic normal C 18 and C 18-24 alcohols or C 18 amine to prepare four alcoholysis products Alc SMAE and two aminolysis products Am SMAE. The reactions of alcoholysis and aminolysis take place on anhydride units of the polymer chains as evidenced by IR and GPC data. The chemical structures of these derivatives of SMAE are suggested. The alcoholyzed and aminolyzed SMAE terpolymers depress pour point of all crudes under test in more extent (by 20-31℃ in use level 500ppm) and beter conformance to varieties of crudes than original terpolymers do.
