摘　　要：大港油田目前已经进入中高含水开发期,聚合物驱油技术应用将越来越广泛。但是目前注聚区存在的较为突出的问题,注聚见效井出砂严重,受益井防砂后液量下降,防砂效果不理想,严重的制约注聚区的效果。通过对聚合物驱防砂工艺的优选,有效的解决了注聚区出砂严重的问题,并在现场的应用中取得较好的效果,产生了较好的经济效益和社会效益。Dagang Oilfield has entered the middle and high water cut development period, and the applica-tion of polymer flooding technology will be more and more extensive. However, at present, there are some prominent problems in the polymer injection zone, such as serious sand production in the polymer injection well and the decrease of the liquid amount after the sand control in the beneficial well. The effect of sand control is not ideal, and the effect of the polymer flooding zone is seriously restricted. By optimizing the sand control process of polymer flooding, the problem of sand production in the injection zone has been effectively solved, and good results have been achieved in field applications, resulting in better economic and social benefits.
