不同类型表面活性剂对煤体的润湿性研究
|
摘要
为了提高现场煤层注水效果,针对润湿性较差煤体,提出采用添加表面活性剂的方法以提高煤体润湿性。以贵州百色集团六龙煤矿煤样为例,根据表面活性剂种类选出4种有代表性且廉价易得的表面活性剂,通过测定纯水和添加表面活性剂的溶液的表面张力及其与煤体的接触角,优选出磺化玻拍酸二辛酷钠盐(快速渗透剂T)作为最佳表面活性剂,最佳浓度为0.4%。
In order to improve the effect of water injection in coal seam, to improve the wettability of coal with poor wettability,surfactant was added. Taking the coal samples of Liulong Coal Mine in Baise Group of Guizhou Province as an example, this paper selects four representative and inexpensive surface active agents based on the species of surfactant. By measuring the surface tension of pure water and adding surface active agent and the contact angle with the coal body, the sulfonated sodium bate acid two octyl sodium salt(fast penetrating agent T) was selected as the best surfactant and the best concentration was 0.4%.
