摘要
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 polymeric oil-displacing agent is studied. Through contrasting it with common performance evaluating method for polyacrylamide, it is found out that influences should be increased such as influence of degree of mineralization and temperature variation on thickening property; influence of elasticity of polymer solution and surfactant on viscosity of polymer solution; influence of Absorption on viscosity of polymer solution; influence of injected slug size and concentration on oil displacement efficiency and analysis of residual resistance coefficient. It is proposed that replacement of measurement of dissolution time and determination of filtration factor with observation of injecting situation should be taken.
