摘要
安徽天长地区阜宁组砂岩储层以细—粉长石砂岩为主。利用岩石薄片、粒度、物性、扫描电镜、X—光衍射、压汞和孔隙结构图像分析等资料,对砂岩的岩石成分、成岩特点、孔隙演化、孔隙类型、孔隙结构等进行了分析研究,在此基础上,对储层进行了分类。
The reservoirs of the Funing Formation in Tianchang Anhui are composed mainly of fine-grained to powder arkose.Based on research data on thin sections,grain size,physical properties,X-ray diffractions, capillary pressures and pore structure image,the paper discussed the lithological composition,diagenetic features,pore evolution,pore types and pore structure.Then an evaluation has been made on classification of sandstone reservoirs.
