摘　　要：白452区经过几年聚驱开发后出现了诸多问题,为了更好地改善区块的聚驱开发效果,研究了区块内大孔道分布状况,对注聚前后大孔道进行对比,结合动态资料,精细研究低效无效循环层形成原因,并提出治理方法。Many problems occurs in Bai-452 block after several years of polymer flooding development.In order to better improve the development effect of polymer flooding in this block,the distribution of large pore paths in the block is studied,and the large pore paths before and after injection are compared.Also,combined with dynamic data,a detailed research on the causes of low and non-effective circulation layer formation is carried out,and relevant adjusting methods are proposed in this paper as well.

关 键 词：白452区 注聚中期 大孔道 低效 无效循环层
