摘要
文章研究了重烷基苯磺酸盐(HABS)/QK-25原油间的界面张力(IFT)。探讨了HABS种类、复配比例和浓度,醇种类和含量,Na2CO3含量和非离子表面活性剂TX-10含量对IFT的影响。结果表明,当金桐2#/南京1#=5∶5时,体系界面张力最低;最优醇类为正丁醇,但醇种类和含量对界面张力影响不显著;TX-10含量、Na2CO3含量和HABS浓度对体系界面张力的影响依次减小。
The interfacial tension of heavy benzene sulfonate /QK-25 crude oil were studied.Factors which influence the test results of IFT were discussed,including the types and mixed ratios and contents of HABS,the types and contents of the alcohol,the contents of Na2CO3 and TX-10.The results showed that IFT has the minimum when the mixed ratio of Jingtong2#/Nanjing1# =5∶5,the types and contents of the alcohol have few effect on IFT.The effect of the content of TX-10 and Na2CO3 and HABS on IFT became weak little by little.
