摘要： 对于富含蒙皂石的粘土砂岩,按常规方法钻取岩心、洗油、烘样,制出来的铸体薄片往往形成人为裂缝,不能真实地反映孔隙特征。为此,提出了一种高蒙皂石砂岩铸体薄片制片新方法,此方法所制出的铸体薄片,反映出的孔隙特征具有保真性,避免了高蒙皂石砂岩样品因脱水收缩造成人为孔隙、人为裂缝等现象。

Abstract: The conventional methods of coring, wash oil and dry sample for making cast thin section from clay sandstone enriched with smectite tend to shape artificial fractures, hence should not reflect the real porosity in it. This paper presents a new method for making such a cast thin section that can be of fidelity by avoiding the artificial porosity and fractures of such a sample due to dehydration and shrinkage.

Key words: smectite, thin section, porosity, method
