摘要
利用 X衍射全岩分析方法、粘土矿物定量分析方法和薄片鉴定等方法研究了城华地区延 8-延 1 0储层岩石学特征和孔隙成因类型 .综合论述了城华地区延 8～延 1 0油组不同岩相储层砂岩的基本特征 ,纠正了砂岩定名的错误和主要填隙物成份的错误 ,同时还论述了储层砂岩的孔隙特征和控制孔隙发育的主要因素 .
The petrologic characteristic and the pore types of Y8~Y10 reservoir are studied by X ray diffraction method, the quantitative mineral clay analysis method and thin section analysis method.Based on the study,the mistakes are corrected in the naming of the sandstone and in the composition of the pore filling substance.The pore characteristic of the sandstone and the main factors of controlling the pore development are discussed.
