摘　　要：借鉴陆地油田聚合物驱油藏筛选标准,结合渤海海域油田聚合物驱室内实验研究结果,对渤海海域油田适宜聚合物驱的油藏进行了筛选和分类;基于不同类型油藏地质、开发条件和经济参数,应用油藏数值模拟手段研究了渤海海域油田聚合物驱的主要影响因素;基于蒙特卡罗模拟法和统计学方法,建立了渤海海域油田聚合物驱潜力评价方法,并对不同地区不同类型油藏进行了聚合物驱提高采收率潜力评价。辽东湾、渤南、渤中等3个地区聚合物驱提高采收率均在5%以上,其中辽东湾地区适合聚合物驱的油藏(区块)有7个,提高采收率潜力最大。Drawing on the reservoir screening criteria for polymer flooding in onshore oilfields and combining results from polymer flooding experiments for offshore fields, reservoirs suitable to polymer flooding are screened and classified in Bohai oilfields. Based on different conditions of geology and development and economic parameters for different types of reservoirs, major factors to control polymer flooding in Bohai oilfields are probed by using a tool of numerical reservoir simulation. A method to evaluate polymer flooding potential in Bohai oilfields is established, according to Monte Carlo simulation and statistics tools, which has been used to evaluate potential to enhance recovery of polymer flooding for different types of reservoir in different areas. The oil recovery factor can increase over 5% through polymer flooding for the reservoirs in Liaodong areas, with 7 reservoirs Bay, Bonan and Bozhong or blocks suitable to polymer flooding in Liaodong Bay where the potential to enhance recovery is the greatest.
