中文摘要：

两亲聚合物（HAP）是一种新型聚合物驱油剂,针对大庆油田驱油用两亲聚合物HAP-570和HAP-1200,利用荧光探针考察其缔合行为。结果表明：随着HAP质量浓度增加,疏水基团之间的缔合性增强;两亲聚合物的相对分子质量越大,临界聚集浓度cCAC值越小;NaCl质量浓度越大,cCAC值越小,且HAP相对分子质量越大影响越显著;Na^＋对cCAC值的影响符合公式lgcCAC=A-Blgc0,其中B值反映Na^＋对cCAC值的影响程度;两亲聚合物增黏能力较强,且黏度-浓度曲线与荧光探针确定的不同相对分子质量的cCAC变化规律具有较好的对应关系。

英文摘要：

The hydrophobic associating polymer（HAP） is a novel oil displacement polymer agent.The association properties of two hydrophobic associating polymers applied in Daqing Oilfield,HAP-570 and HAP-1200 were investigated by using fluorescence probe method.The results show that the aggregation between the hydrophobic groups strengthens with the increase of concentration for the HAP.Furthermore,the larger molecular weight of the hydrophobic associating polymers,the higher concentration of NaCl,the lower value of critical aggregation concentration（CAC） is.And the influence increases with the molecular weight for HAP increasing.Meanwhile,the effects of Na^＋on CAC value accord to the formula,lgcCAC=A-Blgc0,and the value of B reflects the degree for the influence of Na^＋on CAC value.The hydrophobic associating polymer has good thickening ability,and the change rules of CAC value obtained by fluorescence probe have good corresponding relations to the viscosity-concentration curve.
