摘要: 用Washburn法对比了单分子双季铵盐(MD膜驱剂)、四乙基溴化铵[(Et) 4 NB]、十二烷基三甲基溴
化铵(DTAB)、十六烷基三甲基溴化铵(CTAB)单独及复配溶液对粘土润湿性的影响。研究结果表明,以MD膜驱
剂、(Et) 4 NB,DTAB,CTAB单独作为改性剂,粘土吸附MD膜驱剂的亲水性大于(Et) 4 NB,DTAB,CTAB,而亲油性
均小于(Et) 4 NB,DTAB,CTAB。MD膜驱剂分别与(Et) 4 NB,DTAB,CTAB以不同比例复配的溶液改性粘土随着
MD膜驱剂所占比例的增大亲水性增强,亲油性减弱;尤其当MD膜驱剂以较小比例与短链季铵盐(Et) 4 NB复配时,
比(Et) 4 NB单独改性的亲水性明显增强,而亲油性明显减弱

Abstract:  

Washburn method was applied to investigate on the wettability of the organic bentonite modified by molecular deposition filming flooding agent (MDFFA) mixed with tetraethyl ammonium bromide [(Et)4NB], dodecyl trimethyl ammonium bromide (DTAB) or hexadecyl trimethyl ammonium bromide (CTAB). The results show that the organic bentonite absorbed MDFFA is more hydrophilic than that of organic bentonite absorbed (Et)4NB,DTAB,CTAB, then the oil wettability of organic bentonite absorbed MDFFA is lower than others. For the solution of MDFFA mixed with (Et)4NB,DTAB or CTAB, with the increase of MDFFA volume proportion the organic bentonite is more hydrophilic and the oil wettability is lower, especially for the organic bentonite treated by the solution of MDFFA mixed with (Et)4NB, when (Et)4NB mixed with a little MDFFA the organic bentonite is more hydrophilic than that of absorbed (Et)4NB and the oil wettability is lower obviously.
