对新型聚合物驱油剂的应用性能进行了研究。通过与普通聚丙烯酰胺性能评价方法的对比,发现必须增加矿化度、温度变化对增稠性能的影响,聚合物溶液的弹性、表面活性剂对聚合物溶液粘度的影响,吸附对聚合物溶液粘度的影响和不同注入段塞大小和浓度对驱油试验的影响测定及残余阻力系数分析;建议采用注入状态观测取代溶解时间和过滤因子测定。
The application performance of new polymer flooding agent has been studied. Through the comparison with ordinary polyacrylamide performance evaluation method, it is found that it is necessary to increase the influence of the degree of salinity, the change of temperature on the thickening property, the elasticity of the polymer solution, the influence of the surfactant on the viscosity of the polymer solution, Viscosity and influence of different injected slug size and concentration on flooding test and analysis of residual resistance coefficient. It is recommended to use injection state observation instead of dissolution time and filtration factor.
