摘　　要：以储层岩石学特征与成岩作用特征分析为基础,开展甘谷驿油田长6储层成岩相类型划分,并应用压汞资料分析不同成岩相储层孔隙结构及其生产动态差异。结果表明:绿泥石薄膜胶结—粒间孔成岩相的孔隙最发育、孔喉配置关系好、物性好、单井产量高,是最有利的成岩相带,可作为后期勘探开发重点目标区域。Based on the analysis of reservoir petrological characteristics and diagenetic characteristics,the diagenetic facies types of Chang 6 reservoir in Ganguyi Oilfield were divided,and the pore structure and production dynamics of different diagenetic facies reservoirs were analyzed by mercury injection data. The results show that the diagenetic facies of chlorite film cementition-intergranular pore facies has the most developed pores,good pore-throat configuration relationship,good physical property and high single well production,which is the most favorable diagenetic facies belt and can be used as the key target area of later exploration and development.
