| 摘 要： | 高邮凹陷北斜坡储层岩性以细砂岩和粉砂岩为主，砂岩类型主要为岩屑-长石质砂岩。该区23口井岩心砂岩储层铸体薄片及普通薄片的分析结果表明：戍岩作用类型主要有压实作用、胶结作用、交代作用和溶解作用，岩石在埋藏过程中以机械压实作用为主。胶结物主要有碳酸盐岩胶结物和硅质胶结物，交代作用很普遍，杂基与胶结物的溶解对次生孔隙的形成起重要作用，改善了储集性能。根据镜质体反射率和伊蒙混层的成岩界限等，证实研究区储层基本上处于晚成岩A1亚期和晚成岩A2亚期。

| Abstract: | The reservoir lithology is mainly fine sandstone and siltstone in Funing Formation of northern slope,Gaoyou Depression. Sandstone types are mainly debris-feldspathic sandstone. Based on the analysis of casting thin section and common thin section from the cores of 23 wells in study area,the diagenetic types typically comprise the compaction,cementation,metasomatism and dissolution. The mechanical compaction is dominant in the process of burial. Cements are mainly the carbonate cements and siliceous cements.... |
