摘要
测定了烷基苯磺酸盐(KPS)与环烷基石油磺酸盐(HABS-16)不同复配比下的临界胶束浓度与表面张力,考察了不同浓度下复配表面活性剂溶液的增溶量,并进行了岩心驱替实验,研究了复配表面活性剂的驱油效率。实验结果表明,当HABS-16质量分数为0.33时,复配表面活性剂胶束的平均粒径最大,表面张力最低,为22.74 mN/m。相比于单一体系,复配表面活性剂对模拟原油及烷烃、芳烃的增溶能力更强。复配表面活性剂含量越大,驱油效果越好,当复配表面活性剂加入量为1.0%(w)时,驱油效果最好,采收率最高,为81.60%。
The critical micelle concentration and surface tension of alkylbenzene sulfonate(KPS)and naphthenic petroleum sulfonate(HABS-16)at different compound proportions were determined,the solubilization amount of the compound surfactant solutions at different concentrations was measured,and the core flooding experiment was carried out to study the oil displacement efficiency of the compound surfactant.The experimental results show that when the mass fraction of HABS-16 is 0.33,the average particle size of the compound surfactant micelles is the largest,and the surface tension is the lowest,which is 22.74 mN/m.Compared with the single system,the compound surfactant has a stronger solubilization ability to simulate crude oil,alkanes and aromatics.The higher the content of the compound surfactant,the better the oil displacement effect.When the amount of the compound surfactant is 1.0%(w),the oil displacement effect is the best,and the recovery factor is the highest,which is 81.60%.
