摘　　要：针对大庆油田聚驱开发过程中暴露出来的聚合物溶液在高渗层低效注入以及低渗层聚驱动用程度低等问题,对聚驱过程中分层注入参数进行了优化研究,提出了分层注聚的厚度界限、渗透率界限、分层注聚时机和分层注入层段注聚最佳用量,在总体注入量相同的情况下,实现采收率的最大化。During polymer flooding in Daqing oilfield, injection of polymer in high permeability layers is not effective, and the sweeping efficiency for polymer flooding in low permeability is low. Therefore, research on parameter optimization of separate layer injection during polymer flooding has been done systematically. The thickness limit for separate layer polymer injection, permeability limit, time for polymer injection and the optimal volume for polymer injected are established to reach the maximized recovery factor.
