| 摘 要： | 利用钻井岩心、铸体薄片、扫描电镜及地球化学等分析资料对贝中次凹南屯组一段储层发育特征进行了系统的研究.结果表明:贝中次凹南屯组一段属于中低孔一低渗、特低渗储层,岩性以长石岩屑砂岩和长石砂岩为主,成分成熟度和结构成熟度均较低,储层的储集空间主要为次生孔隙.沉积环境、有机质演化中产生的有机酸、烃源岩与储层的组合关系以及碳酸...

| Abstract: | The development characteristics of the first member of Nantun Formation reservoir is studied systematically by using data of core，casting thin sections，SEM and geochemical analysis in Beizhong sub depression.The result shows that it is medium and low porosity，low and ultra low permeability reservoir.Its lithology is mainly feldspathic lithic sandstone and feldspathic sandstone.The reservoirs compositional maturity and texture maturity is lower，and the main reservoir space is secondary pore.The sedimentary micro facies，organic acid produced by organic matter evolution，the syntagmatic relation of source rock and reservoir，and the carbonate content are the main factors effecting the reservoir effectiveness. |
