摘　　要：测试了疏水缔合羟乙基纤维素（BHEC）阻力系数和残余阻力系数,并与未改性羟乙基纤维素（HEC）做对比.实验结果表明：BHEC阻力系数和残余阻力系数均随着聚合物浓度的增加而增大,当浓度超过BHEC临界缔合浓度时,其阻力系数和残余阻力系数由增加平缓变为急剧上升;随着渗透率的增大单调减小,阻力系数为12～21,残余阻力系数为6～10;随着注入速率的增加而单调递增,但增加幅度较小;随着温度的上升而下降.The RF and RRF of the hydrophobically associating hydroxyethyl cellulose （BHEC） were investigated in laboratory by the solution of the artificial core displacement experiment in comparison with unmodified hydroxyethyl cellulose （HEC）.The result of experiment indicates that the RF and RRF of BHEC were significantly increased with the increase of polymer concentration,especially when BHEC achieved a certain concentration.It was monotonously decreased with permeability of porous media increasing.The RF of BHEC was 12-21 and the RRF of BHEC was 6-10,which were higher than that of HEC.The RF and RRF of BHEC were monotonously increased with the increase of injection rate while decreased with the increase of the temperature,also much higher than that of HEC.
