聚合物驱油技术作为稠油油田开发稳产或增产的重要手段之一，在国内外陆上油田已取得了广泛应用。为了探索聚合物驱油技术在海上稠油油田应用的可行性，渤海油田在3个油田实施聚合物驱开发模式，历经12年，共有44口注聚井，179口受益井，取得了明显的聚合物驱增油降水效果。但是，在聚合物驱开发过程中，部分受益井产液量下降，大大影响了聚驱油田的开发效果。通过分析，发现主要原因为聚合物在油井近井地带产生堵塞，造成泵效降低，经过相应治理措施后效果明显，为后期聚驱油井的开发提供了参考依据。

As one of the most important technology for the development of heavy oil reservoirs,polymer flooding is widely used in onshore oilfields both at home and abroad.In order to explore the application feasibility of polymer flooding technology in offshore heavy oil fields,three reservoirs in Bohai oilfields have implemented the polymer flooding develop-ment mode.For 12 years,the technology has gained obvious effects,with oil production increasing and water cut decreas-ing in 44 polymer injection wells and 179 oil wells.However,oil production decreasing happened in some oil wells, influencing the effect of polymer flooding.The main reasons were the formation plugging and lower pump efficiency caused by the polymer.After taking corresponding control measures,the problems have been well solved.The results can provide reference and technical support for the polymer flooding application in offshore oilfields.
