摘　　要：针对中高渗透水驱油藏特高含水阶段剩余油赋存方式的变化情况,室内研制了具有选择性的聚合物体系,该体系具有T型稳定结构,因此称为T型聚合物。在实验室对T型聚合物进行了性能评价研究,研究结果表明:随着聚合物浓度升高,T型聚合物黏度呈上升趋势,聚合物的质量浓度为1500 mg/L时黏度达到125 mPa·s;高弹性T型聚合物溶液具有较弱的盐敏效应;85℃恒温箱放置90 d黏度保留率达到82.4%,体系具有良好的热稳定性。In consideration of the change of remaining oil occurrence in super high water cut stage of high permeability water flooding reservoir,a selective polymer system was developed in laboratory test.This system is called T-polymer because it has T type stable structure.The performance of this T-polymer was studied in laboratory,and the results of study have shown that the viscosity of T-polymer increases as the concentration of polymer increases and that the viscosity of polymer reaches 125 mPa.s when its concentration is 1500 mg/L.The solution of high elasticity T-polymer has weak salt sensitivity effect,and the viscosity retention rate of polymer reaches 82.4%after it has been placed in a constant temperature oven for 90 d showing that this system has good thermal stability.
