摘要
定量测定泥页岩的表面水化水和渗透冰化水有助于认识其水化机理,分析水化对井壁稳定的影响,还有助于研制抑制性处理剂。介绍了泥页岩水化水的定量分析方法。结果表明,用水汽等温吸附法测定表面水化水量,用膨胀法测膨胀水量进而计算渗透水化冰量的实验研究方法是可行的。
Shale hydration is one of the factors that lead to the instabilization of the hole. Quantitative assay of surface and permeated hydration water is difficult, while it really help to understand the hydration mechanism and its influence on hole stabilization, it could also help to develop new inhibitors. The paper describes an approach of quantitative analysis, which is applying Isothermal Adsorption Method to determine surface hydration water, and Dilatometric Method to calculate the permeation. Result proved it to be practical.
