摘　　要：根据岩心、铸体薄片、压汞、扫描电镜、物性等资料,对四川盆地普光地区长兴-飞仙关组礁滩型储层的微观非均质性(岩石成分非均质性、孔隙结构非均质性、孔隙类型非均质性、裂缝类型非均质性)特征进行了系统的研究。结果表明:普光地区长兴-飞仙关组储层在岩石成分和孔隙结构上表现出较强的微观非均质性,而在孔隙类型和裂缝类型上表现出弱非均质性。综合分析认为,普光地区长兴-飞仙关组礁滩型储层为中等微观非均质性储层。该研究方法对相似地区的礁滩型储层微观非均质性研究有借鉴意义。Based on date of cores,casting slice,scanning electron microscopy , mercury pene- tration and physical properties, the reef reservoir microscopic heterogeneity （rock composi- tion heterogeneity and pore structure heterogeneity, pore type heterogeneity, fracture type heterogeneity） characteristics of Changxing-Feixianguan formation of Puguang area are sys- tematically studied. The result shows that： the rock composition and pore structure display strong microscopic heterogeneity. However, the pore type and fracture type heterogeneity is not strong.The comprehensive analysis shows that the reef reservoir of Changxing-Feixian- guan formation in Puguang gasfield is medium microscopic heterogeneity reservoir. This re- search method has significant reference for microscopic heterogeneity study of reef reservoir in similar areas.
