通过岩心镜下薄片和电子探针对粘土矿物的含量分析，得出东河油田1井区石炭系东河砂岩段储层粘土矿物以高岭石为主，其次是伊利石，伊蒙混层和绿泥石矿物含量低。粘土矿物结构较稳定。结合岩心敏感性测试分析得知，东河砂岩段储层主要以碱敏和酸敏为主。所以在注水开发过程中，要防止碱敏和酸敏对储层的伤害。
通過巖心鏡下薄片和電子探針對粘土礦物的含量分析，得齣東河油田1井區石炭繫東河砂巖段儲層粘土礦物以高嶺石為主，其次是伊利石，伊矇混層和綠泥石礦物含量低。粘土礦物結構較穩定。結閤巖心敏感性測試分析得知，東河砂巖段儲層主要以堿敏和痠敏為主。所以在註水開髮過程中，要防止堿敏和痠敏對儲層的傷害。

On the basis of the observation of microscopically thin slices of the core and the electron probe, this study analyzes elements of clay minerals and concludes that kaolinite occupies the first position of Donghe Sandstone Section of Carboniferous System of Well Area 1 of Donghe Oil Field and illite takes the second while goeschwitzitend reattite and chlorite account for the least.Minerals of clay have a relatively stable structure.Reservoir of Donghe Sandstone Section therefore is alkali and acid sensitive one.And as a result,the reservoir damage from the alkali and acid sensitivity should be prevented in the process of the development with water-flooding.
