研究了几种主要造岩矿物的碱溶规律。通过静态浸泡后上层清液中Ｓｉ、Ａｌ和ＯＨ－含量的测定，得出了固液比、浸泡时间、碱浓度、浸泡温度、碱类型等单一因素对不同矿物碱溶过程影响的规律。研究结果表明，延长浸泡时间、提高碱浓度、升高反应温度有利于矿物溶解；强碱促进矿物溶解；碱化处理的适宜碱剂为ＫＯＨ，适宜地层为高粘土含量的高温低渗砂岩地层
Several alkali rock dissolution laws were studied. Through the determination of the contents of Si, Al and OH- in the supernatant after static soaking, the influence of single factor such as solid-liquid ratio, soaking time, alkali concentration, soaking temperature and alkali type on the alkaline dissolution of different minerals was obtained. The results show that prolonging the immersion time, raising the alkali concentration and increasing the reaction temperature are beneficial to the dissolution of minerals; strong alkali promotes the dissolution of minerals; suitable alkaline agent for alkalization is KOH, suitable for high temperature and low permeability sandstone formation with high clay content
