济阳坳陷孤北斜坡带中生界碎屑岩有效储层成因机制
|
摘要
综合运用岩心观察、铸体薄片鉴定及扫描电镜分析等技术手段,在储集空间特征研究的基础上,分析济阳坳陷孤北斜坡带中生界有效储层物性控制因素,总结有效储层成因机制,建立有效储层成因模式。结果表明,储集空间以次生孔隙为主。辫状河三角洲前缘的水下分流河道及冲积扇的扇中辫状河道砂岩是有效储层形成的物质基础。研究区经历了"一次中埋—抬升剥蚀—二次深埋"的构造演化过程,早期碳酸盐岩胶结保护原生孔隙,是有效储层形成的主控因素。二次深埋后的油气充注形成大量的次生孔隙,是有效储层形成的关键要素。
This paper synthetically uses core observation, casting thin sections identification and electronic scanning techniques to analyze the controlling factors for the effective reservoir in the Mesozoic of the isolated north slope zone in Jiyang Depression baed on the research of the characteristics of the reservoir space, summarizes the effective reservoir formation mechanism, and establishes an effective reservoir formation mode. The results show that the reservoir space is mainly secondary porosity and that the braided channel sandstone is the material foundation of effective reservoir formation in the underwater distributary channel and fan of alluvial fan in braided river delta. The study area underwent the tectonic evolution of "one burial-uplift denudation-secondary deep burial", and early carbonate cementation protected primary pores, which was the main controlling factor of effective reservoir formation. A large number of secondary pores are formed after the second deep burial, which is the key factor for the formation of effective reservoir formation.
