| 摘 要： | 利用铸体薄片、扫描电镜及X射线衍射等分析资料对鄂尔多斯盆地东部主要含气层系黏土矿物的特征进行分析,盆地东部黏土矿物主要受物源区母岩、沉积相和成岩作用特征等方面影响,不同层系黏土矿物受影响程度不同,其中二叠系石千峰组千五段和石盒子组盒八段受物源区母岩和沉积相影响较大,山西组二段和太原组受成岩作用和沉积相影响作用明显;加强对不同层系黏土矿物的特征研究,可明确主要含气层系储层的潜在敏感性,这个初步结论对有针对性地保护储层和储层改造具有一定的借鉴意义。

| Abstract: | Abstract:Based on study of thin-section analysis, "X" diffraction and scanning electricity microscopy observation analysis, the basic characteristics of the main layers of clay minerals has been sysernatically reserched in eastern Ordos Basin.It is indicated that the characteristics of clay mineral is affect by source rock, sedimentary facies and diagenesis. The controlling factors of clay minerals of different layers were different.Such as, in the 5th section of Shiqingfeng formation and the 8th section of Shihezi formation, controlling factors are source rock and sedimentary facies, but in the 2th section of Shanxi formation and Taiyuan formation, diagenesis and depositional facies influence are impotrant. To strengthen the study on the characteristics of clay minerals of different layers, the potential sensitivity of main reservoircan be clearly maked out, and this preliminary conclusion may play certain reference significance to the protection and renovation of reservoir. |
