渤海油田自2003年开始实施聚合物驱提高采收率技术，取得了一定的降水增油效果，但海上油田聚合物驱 规模不断扩大也给地面油水处理带来诸多挑战。基于海上聚合物驱油田产出液处理现状，分析了含聚合物产出 液油水分离、含聚合物污水处理、含聚合物油泥处理和污水回注过程中存在的问题，总结了近年来为解决聚合物 驱产出液处理问题而开展的相关研究，对海上聚合物驱油田破乳剂、清水剂和解堵剂的开发有一定的指导意义， 为进一步提高海上油田聚合物驱产出液处理能力、改善油水处理效果、减少聚合物油泥和提高油水井解堵效果 提出了建议。

Bohai oilfield had achieved some results of increasing oil production and decreasing water cut after polymer flooding enhanced oil recovery technique was implemented since 2003. But the increasing scale of polymer flooding brought many challenges to the treatment of crude oil and water on platform. The problems on oil- water separation of polymer- containing produced fluid，treatment of polymer-containing wastewater，treatment of oily sludge and wastewater reinjection were analyzed，on the basis of the status of produced fluid treatment in offshore polymer flooding oilfield. Studies on the treatment of polymer-flooding produced fluid in rencent years had significant instruction for the development of demulsifiers，water clarifiers and plug removal agent in offshore polymer flooding oilfield. The recommendations concerning further improving the processing capacity of polymer flooding produced fluid，enhancing the treatment effect of crude oil and wastewater，reducing the amount of oily sludge and increasing the efficiency of removing plug of oil or water well in offshore oilfield were provided.
