摘　　要：在深入分析海上稠油聚合物驱提高采收率的难点与挑战的基础上,通过近10年的攻关和矿场试验,研制出适合海上稠油油藏条件的驱替液技术、平台聚合物配注技术、海上稠油含聚采出液处理技术及早期注聚效果评价等一系列技术,初步形成了海上油田聚合物驱油技术体系,并在渤海绥中36-1、旅大10-1及锦州9-3等3个油田进行了不同规模的现场试验,取得了明显的增油降水效果。证明了聚合物驱提高采收率技术在海上稠油油田应用的技术可行性和经济有效性,为海上油田高效开发探索出了一条崭新的道路,具有广阔的应用前景。Although there is a high development potential,the EOR（enhanced oil recovery） techniques of onshore oilfield are not suitable for offshore.Based on the 10 years research and analysis of EOR techniques of offshore thickened oil,a series of resolutions and techniques on driving fluid technology,platform polymer injection distribution technology,production containing polymer treatment technology and effectiveness evaluation of early polymer injection for offshore heavy oil were developed,the system of offshore polymer flooding were established.These techniques had been carried out in Suizhong36-1,Lvda10-1 and Jinzhou9-3 with large scale field experiments.The water was controlled at a low level and the oil extraction was enhanced.These works proved the feasibility of the techniques and the value of economy.
