| 摘 要： | 基于24口井岩心铸体、岩石薄片的测试数据及砂岩微观结构的观察，分析了溱潼凹陷北坡阜三段碎屑岩储层的岩石学特征、不同沉积微相砂岩的物性特征、储集空间特征、成岩作用及成岩演化特征。研究结果表明本区东西部阜三段储层在沉积微相、岩石学特征、储集空间、成岩特征等方面都存在着一定的差异。指出较好的储层位于本区莫庄北部的上下砂组及茅山北部、叶甸—边城西北部的上砂组中；同时认为次生孔隙在纵向上具有一定的分带性，其主要分布在埋深2350m～2880m。最后对本区储层进行了评价和预测．

| Abstract: | The study area may fall into four working areas, they are Mozhuang, Maoshan, Yedian-biancheng and Dainan. Mozhuang lies in the east, Dainan in the middle, Maoshan in the northwest and Yedian-biancheng in the southwest of the study area. Based on the observation of the foundry, testing data from the rock section and the micro-texture of sandstone of the core samples from Well 24, the lithological characters of the clastic rock reservoir, physical properties of sandstone in different micro sedimentary facies, properties of reservoir space, diagenesis and diagenetic evolution features of third member of Funing Formation in the north slope of Qintong depression. It is concluded that there exists certain difference in the aspects of micro sedimentary facies, the lithological characters, properties of reservoir space and diagenetic evolution features in the west and east parts of third member of Funing Formation. It is stated that the favorable reservoir is located in the upper and lower sand formations in the north of Mozhuang, the upper sand formations of north Maoshan and northwest of Yedian-biancheng; Meanwhile, it is stated that the secondary fissures are possessed with certain zonation longitudinally, distributing mainly in the burial of 2 350 m to 2 880 m. The reservoir in the study area is evaluated and predicted by the author as a conclusion of the paper. |
