| 摘 要： | 摘要本文着重介绍了在实验测定聚合物溶液残余阻力系数(FRR)时所发现的一种特殊现象—FRR的时间相关性。可以认为这是滞留在多孔介质中聚合物分子当注入水流速变化时产生的附加残余效应。本文定义了附加残余效应系数(FARE)。根据部分水解聚丙烯酞胺(HPAM)水溶液在力场作用下分子构象的变化，分析了粘弹性可能是产生附加残余效应的根本原因，岩心渗透率是影响FARE的一种因素。作者认为存在着利用这种效应进一步改善流度控制的可能性。

| Abstract: | Time-dependent characteristics of the have been found experimentally. It can be residual resistance factor (FRR) visualized as an additional residual effect (FARE) produced by the retained polymer molecules while of the injection water is changed. And the additional residual the flow-rate effect factor (FARE) has been defined. Theoretical analyses based on comformation changes of the polymer molecules in a varying flow field indicate that polymer viscoelastic property is essentially responsible for this effect. |
