摘　　要：以蓬莱气区灯影组碳酸盐岩储层为研究对象,利用X-射线衍射、扫描电镜、铸体薄片、高压压汞、核磁共振等分析测试手段,系统分析储层岩性、物性、孔隙结构特征,在此基础上对储层进行分类评价,明确储层物性下限,为蓬莱气区灯影组储层评价和储量规模确定提供技术支撑。This project takes the carbonate reservoir of the Dengying Formation in the Penglai gas area as the research object,and uses analytical testing methods such as X-ray diffraction,scanning electron microscopy,cast thin sections,high-pressure mercury injection,and nuclear magnetic resonance to systematically analyze the lithology and physical properties of the reservoir.,pore structure characteristics,on this basis,the reservoirs are classified and evaluated,and the lower limit of the reservoir physical properties is clarified,which provides technical support for reservoir evaluation and reserve scale determination of the Dengying Formation in the Penglai gas area.
