| 摘 要： | 针对目前砂岩储层酸化常规酸液体系在酸化过程中反应速度过快、有效作用距离短、易生成二次沉淀等缺陷,提出一种新型砂岩酸化MFC酸液体系。酸度特性、溶蚀率和配伍性等室内实验表明:该酸液体系能有效地溶蚀粘土矿物,且与粘土矿物的反应速度慢,有利于抑制二次沉淀;MFC酸液体系在与砂岩矿物反应过程中H+浓度降低缓慢,具有良好的缓速作用;与各种酸化用添加剂能良好的配伍,酸液润湿性为水湿;MFC酸液体系对砂岩储层具有好的酸化流动效果。

| Abstract: | View of the defects of conventional acidizing fluid system for sandstone acidization including too fast speed,short effective operation distance,and easy to generate secondary sediment,it develops a new type of MFC acidizing fluid system for sandstone acidization. Based on the experiment about the acidity,corrosion,compatibility,corruption,fluidity of the new MFC system,it shows that the corrosion of MFC is very effectively to clay mineral,and the reaction is slow,which is better inhibition of secondary pre... |
