根据粘土矿物X衍射和扫描电镜等测试分析,乌夏断裂带三叠系储层粘土矿物类型主要为伊/蒙混层、伊利石、高岭石和绿泥石。粘土矿物平面分布具有分区性,从风城地区、夏子街地区至乌尔禾地区高岭石含量逐渐降低。粘土矿物相对含量纵向具有分异性,百口泉组储层伊/蒙混层相对含量较高,克下组与克上组储层高岭石相对含量则较高。研究表明本区粘土矿物特征及分布受沉积环境、古气候及地层水介质等因素控制。
Based on the X-ray diffraction and scanning electron microscopy (SEM) analysis of clay minerals, the clay minerals in the Triassic reservoir rocks in the Wuxia fault zone are mainly Iraqi-Mongolia mixed layer, illite, kaolinite and chlorite. The planar distribution of clay minerals is zonal. The content of kaolinite from Fengcheng area, Xiazijie area to Wuerhe area gradually decreases. The relative content of clay minerals is longitudinally divergent, while the relative content of Iraq / Mongolia mixed layer in Baikouquan Formation is relatively high. The relative content of kaolinite in Kexia Formation and Kejia Formation is higher. The results show that the characteristics and distribution of clay minerals in this area are controlled by factors such as sedimentary environment, paleoclimate and formation water medium.
