| 摘 要： | 热解除油是目前室内岩心分析中样品除油的主要方法之一，但由于热解温度较高，会对样品中粘土矿物的结构水和层间水产生较大的影响。本文结合粘土矿物的吸水特性，通过对大量的实验测定结果分析后认为：经过热解处理后的样品，在测定过程中受粘土矿物（主要是伊利石和蒙脱石）层间水变化的影响，会引起样品重量及样品孔隙空间体积的变化，从而对物性分析中孔隙度测定结果产生较大的影响。

| Abstract: | Pyrolysis is one of dominent deoiling methods for core samples in lab now. However,its high temperature has great effects on the structural and interformational water inside the clay mineral ofthe sample. In the light of hydroscopicity of the clay minerals,the following facts are found through analyses on a large quantities of lab measurements : after pyrolysis process,the weight and pore volume of thecore samples will change with the interformational water content of the clay minerals(mainly including illite and montmorillonite),thus its influence on porosity measurements is proved evidently. |
