摘　　要：通过物理模拟方法,研究杏北油田二类油层聚合物相对分子质量、注入速度、段塞大小、聚合物溶液黏度、不同注聚方式对驱油效果的影响.结果表明:杏北油田二类油层可以进行清水配、污水稀释聚合物溶液驱油;适合的聚合物相对分子质量为2500×104,注入速度为1.0m/d,注入孔隙体积倍数为0.8PV,注入黏度为65mPa.s;周期注聚方式可以降低注入压力.Researches have been carried out in the second reservoir by physical modeling method to find out the formula weight of the polymer、injection rate、slug size and viscosity of the polymer solution.Results show that different methods of polymer flooding affect the displacement characteristics respectively.The result indicates that Xingbei second reservoir convinced that we can adopt clear water to make up the polymer solution and use the sewage to desaturate polymer solution to displace oil.Polymer molecular weight is 2 500×104,injection rate is1m/d,influx is 0.8 PV,viscosity is 65 mPa·s.Cycle polymer flooding method can reduce injection pressure.
