摘要
介绍了一类适用于高矿化油藏的阴离子表面活性剂。研究了NaCl浓度、表面活性剂浓度、烷烃数对CY表面活性剂水溶液与癸烷间的界面张力,结果表明:CY在高矿化度下与不同烷烃间的界面张力均能达到超低(<10^(-2)mN/m),且具有抗稀释的特点。
The paper introduced a series of anionic surfactants suitable for high salinity oil reservoir, and investigated the effect of NaC1 concentration, surEac^mt concentration ,and alkane carbon number on the interfacial tension （IFT） between CY aqueous solution and decane. The results indicated that CY achieves ultralow IFT （〈10-2 mN/m） against a wide range of ACN, and presents the characteristic of dilution tolerance at high s.linity oil reservoir.
