Abstract: Based on analyses of clay minerals in cores and sand samples obtained before and during the steamflooding process of Qigu formation (Upper Jurassic) viscous oil reservoir in District No. 9, Karamay oilfield, how and why the content and composition of clay minerals vary are discussed. The result can be used for reference in the course of investigation of reservoir damage in the steamflooding process.

Key words: Viscous oil reservoir, Clay mineral, Composition, Content, Origin, Steam injection
