摘　　要：利21块进入特高含水开发阶段,水驱挖潜难度越来越大,需要采用聚合物驱油技术大幅度提高原油采收率.针对L 21油藏高温的特点,在进行聚合物驱配方设计时重点考虑聚合物的耐温抗水解能力,研制成功了新型交联聚合物体系.在此基础上进行了物理模拟和数值模拟研究,对交联聚合物驱浓度、段塞尺寸等参数进行模拟,优选出了交联聚合物驱的工艺方案,并对其驱油效果进行了预测及评价.Li 21 block entered the development stage of high water cut, water flooding is more and more difficult, requires the use of substantial oil polymer flooding technology to enhance oil recovery. According to the characteris- tics of L 21 reservoir temperature, the polymer flooding formula design focus on polymer temperature resistant to hydrolysis, the successful development of a new cross - linked polymer system. On the basis of the research of physical analysis and numerical simulation, the cross - linked polymer flooding concentration, slug size and other parameters are simulated, optimized process was cross-linked polymer flooding, and the oil displacement effect of the prediction and evaluation.
