以正己烷为油相,以Na2 CO3-重烷基苯石油磺酸盐-HPAM (相对分子量1.2×107~1.6×107)三元溶液为水相,用T racker全自动液滴表面张力仪在45℃条件下测量不同浓度弱碱的三元复合体系/油界面扩张黏弹性。阐述了弱碱三元复合驱体系/油界面扩张黏弹性随扩张频率和碱浓度的变化规律。结果表明:随着碱质量分数的增加,三元复合体系/油界面扩张黏性模量、弹性模量都在弱碱质量分数为0.4%时出现极大值;随着扩张频率的增加,碱质量分数为0.4%的三元复合体系界面扩张弹性模量、黏性模量均呈下降趋势;其他碱含量的三元复合体系界面扩张弹性模量呈略微上升的趋势,界面扩张黏性模量基本不变且值非常小。

Interface dilation viscoelastic properties of ASP flooding system with diffirent weak alkali concentration at oil/water interface are measured by the Tracker automatic liquid interface tensiometer produced by I .T .Concept company in French in 45 ℃ condition .In the experiment ,n-hexane is oil phase , water phase is ASP solution which is composed of Na2CO3 , heavy alkylbenzene sulfonate and HPAM (molecular mass is 12 million-16 million) .This paper states the change rules of interface dilation viscoelastic properties of ASP flooding system with different weak alkali concentrations at oil/water interface with expansion frequency and alkali concentration .The results show that with the increase in alkali concentration , the oil/ASP solution interface dilation viscoelastic modulus reaches the maximum at the sodium bicarbonate concentration of 0 .4% .With the increase in frequency ,the interfacial dilation viscous modulus and elastic modulus of ASP solution with 0 .4% alkali concentration are decreased .The interfacial dilation elastic modulus of ASP solution with other alkali concentration is increased slightly and interfacial dilation viscous modulus is almost the same .
