摘要
讨论了大庆减二线原油磺化后制得的石油磺酸盐ＰＳＤ－２与ＮａＯＨ．３３３０Ｓ聚合物组成的三元复合体系／大庆原油间的动态界面张力特性，对ＰＳＤ－２体系，ＰＳＤ－２－ＮａＯＨ体系与大庆原油间的动态界面张力特性进行的比较得知：ＰＳＤ－２体系，ＰＳＤ－２－ＮａＯＨ体系及三元复合体系与大庆原油间的界面张力值对时间有明显的依赖性。随着时间的增加，界面张力下降，大约在１５ｍｉｎ各体系界面张力达到极低值，然后，界面张力逐渐上升，在４５ｍｉｎ左右二元复合体系和三元复合体系又出现了第２个极低值。在１ｈ左右，界面张力达到稳态值。碱的加入使ＰＳＤ－２体系／大庆原油间的动态界面张力普遍降低。
Abstract The performance IFT behavior between petroleum sulfonate PSD-2 preduced from sul- fonated Daqing crude oil /NaOH/POlymer 3330S triaxial eomposite system and Daqing crudeoil has been discued in this paper,and compared with performance IFT of PSD-2 system/Daqing crude oil and PSD-2-NaOH system/Daqing crude oil.The results show that IFTvalues of PSD-2 system/Daqing crude Oil,PSD-2-NaOH system/Daqing crude oil and triaxi- al composite system/Daqing crude oil have an apparent dependency on time. As the time in-creases, IFT will decrease and reach a minimun in about 15 mins for each system,then in- crease slowly and the second minunum occur in about 45 mins for binary and triaxial com-posite systems. For all systems,IFT can reach steady-state value in about one hour.Theaddition of alkali can generally decrease the performance IFT between PSD-2system andDaqing crude oil.
