| 摘 要： | 制备了三种不同ＥＯ数的聚氧乙烯烷基酚磷酸酯（ＯＰＰ－ｎ），考察了它们对正烷烃／石油磺酸盗－异丁醇－盐水体系的界面张力行为。结果表明，这类磷酸酯与前人所用的ＫｌｅａｒｆａｃＡＡ－２７０对盐浓度有相似的展宽的效益。对克拉玛依原油／ＡＳＰ复合体系，亦有展宽作用，ＯＰＰ－１０使界面张力向高盐度区单调下降，而ＯＰＰ－４可使低张力区在较低盐度区展宽。

| Abstract: | Polyoxyethylene alkylphenol phosphates (OPP-n)with different energy group numbers were prepared.The effects of OPP-n on the broadening salinity ranse for achieving low in terfacial tension were studied. For n-alkane/petroleum sulphonate-IBA brine system,the interfacial tension behavior was similar to the previous work by K.S. Chan and D.O. Shah, in which Klearfac AA-270 was used. OPP-n shwwed broadening effects for crude oil/ASP systems. OPP-10 can be conveniently used at high salinity, while OPP-4 used at low salinity. In addition, OP-Pn gave a good compatibility between petroleum sulphonate and polyacrylamide in ASP system. |
