耐油起泡剂的耐油耐盐性能评价
|
摘要
以吴茵搅拌器法评价了由非离子表面活性剂、阴非离子表面活性剂和稳泡剂辛醇按一定比例配制的4种耐油起泡剂的耐油耐盐性能。研究结果表明:随着起泡剂质量分数的增大,起泡剂溶液的最大泡沫体积逐渐增大,在起泡剂质量分数为0.01%数0.5%范围内,起泡剂溶液的发泡体积是自身溶液体积的2数6倍,泡沫半衰期随着表面活性剂浓度增加而逐渐增大;随着原油比例增加,最大泡沫体积先增大后降低,油含量在10%数20%范围时起泡剂表现出了很好的起泡、稳泡性能,最大发泡体积是自身的5数9倍,泡沫半衰期随着油含量增加而明显增大;其中CFE149X(非离子表面活性剂、阴非离子表面活性剂和稳泡剂辛醇质量比为30∶67∶3)的起泡和稳泡性能最佳。在CFE149X质量分数为0.5%、含油量50%的条件下,最大泡沫体积和半衰期均随盐含量增加而先增大后减小;与无油存在时相比,有油存在时泡沫发泡体积略有降低,但泡沫稳定性却显著增强。耐油起泡剂CFE149X,在含油条件下表现出了较好的起泡性能和稳泡性能,能够作为耐油抗盐泡沫剂,为泡沫复合驱提供优良的起泡剂产品提供技术参考。表5参27
The performance of oil-resistance and salt-resistance of 4 kinds of foaming surfactants,composed of a non-ionic surfactant,a non-ionic surfactant and the stabilizer octanol, was evaluated by Wuyin agitator method. The results showed that with the surfactant concentration increased,the volume of foam increased gradually,and the foaming volume was 2—6 times the volume of its own solution at the surfactant concentration of 0.01% —0.5%. Foaming half-life increased with the surfactant concentration increased. With the proportion of crude oil increasing,the maximum foaming volume increased first and then decreased. 4 kinds of foaming surfactants showed good foam capacity when the oil content was of 10% —20%,the maximum foaming volume was 5—9 times volume of its own solution,and the half-life increased obviously with the increase of oil content.CFE149X,a mixture of non-ionic surfactant,non-ionic surfactant and the stabilizer octanol with mass ratio 30∶67∶3,had a good foaming stability and foaming performance in the presence of oil. When the surfactant concentration was 0.5% and the oil content was 50%,the foaming volume and the foaming half-life increased first and then decreased with the increase of salt content.Compared with the system without oil,it was showed that the maximum foaming volume was lower;however,the foam stability was significantly enhanced. The oil-resistant foaming surfactant CFE149X could be used as oil-resistant and salt-resistant foaming surfactant to provide foaming surfactant products of foaming flooding for the reservoir application.
