摘　　要：就烘干法定量分析粘土岩水合程度、水合状态进行了探索性实验研究 ,确定了烘干时间 ,并与等温吸附法、热失重分析法结果进行了对比研究。结果表明 ,合适的烘干时间为 12h ,该方法结果与等温吸附法、热失重分析法结果极为吻合。用它来定量确定鄯善吐哈七克台层位泥岩水合程度、水合状态和评价无机盐抑制泥岩水化能力 ,获得了满意结果。可见 ,用烘干法定量研究粘土岩水合程度、水合状态 。Hydration degree and hydration state of claystone have been studied quantitatively by stove method, in which stove time has been determined and the results of isothermal adsorption and thermal weight loss analysis have been compared. Results show that the suitable stove time is 12 hours, and results of stove method are identical to that of isothermal adsorption and thermal weight loss analysis. In addition, the satisfying results have been obtained by using the method to quantitatively determine the hydration degree and hydration state of mudstone in Shanshan-Tuha Qiketai and to evaluate inhibition ability of inorganic salts. It is practicable that the stove method can be used to quantitatively determine hydration degree and hydration state of claystone.
