摘　　要：分析了聚合物驱深度调剖的机理,并进行了矿场深度调剖试验.试验结果表明:影响深度调剖的主要参数是调剖剂残余阻力因数、聚合物溶液黏度和调剖剂用量;残余阻力因数和调剖剂用量越高,封堵效果越好;聚合物溶液黏度超高,开发效果越好;注入速度和不同段塞组合,对最终采收率影响不大.On the basis of analyzing the mechanism of depth profile modification by polymer flooding, the depth profile modification tests are carried out. The result shows that the main parameters that affect deep profile consist of residual resistance coefficient, viscosity of polymer solution and amount of profile control agent. The bigger the residual resistance coefficient and/or the larger the amount of profile control agent, the better the plugging result can be produced. The higher the viscosity of polymer solution, the better the result. While the injection rate and various combinations have little effect on the ultimate recovery rate.
