摘要
利用滚动分散、ＣＳＴ值测定和页岩稳定指数测试等方法，对比研究了十余种不同阴离子钾盐的抑制页岩水化分散作用。研究发现，钾盐的抑制作用效果不仅取决于Ｋ＋的浓度，而且受钾盐的阴离子种类的影响。在Ｋ＋浓度相同条件下，硅酸钾的抑制能力最强，且硅酸盐的模数和浓度越高，其抑制作用越强。该实验研究对发展和完善钾盐防塌钻井液体系。
The inhibition of shale hydration using potassium mud with different anions are comparatively studied by means of rolling dispersion, CST value measurement and shale stability index etc.. The study discovers that the inhibition of anionic potassium muds depend on not only K+ concentration but also types of anions. For instance, when K+ concentration is the same ,the inhibition effectiveness of potassium silicate mud is the best.
