摘要(Abstract)：

水溶性星形聚合物以功能性基团为星核,在星核上连接3~5个长链线性聚丙烯酰胺链,不仅增黏性能良好,还具有较好的耐温抗盐能力.研究胜利油田高温高盐油藏条件下线形聚合物MO-4000及星形聚合物SD-6800溶液的增黏性能、耐温性能、抗盐性能、抗钙性能和长期热稳定性;通过物理模拟实验分析聚合物MO-4000及SD-6800溶液的阻力因数、残余阻力因数和驱油效率等性能.结果表明:星形聚合物SD-6800溶液的表观黏度可以达到31mPa·s,耐温抗盐性能优于聚合物MO-4000溶液的;在温度75℃、总矿化度19 334mg/L(二价阳离子514mg/L)条件下,热老化90d后,聚合物SD-6800溶液的表观黏度可以达到27mPa·s.星形聚合物SD-6800溶液的综合性能优于线形聚合物MO-4000溶液的.
