    A Study on Hydrocarbon Sources and Accumulation Time in the Northern Fault Zone, Songnan-Baodao Sag of Qiongdongnan Basin

    • 摘要: 琼东南盆地松南-宝岛凹陷北部断阶带发现多个含气构造,对该区带油气来源等认识存在很大争议,深水区烃源岩规模研究方面还比较薄弱,阻碍了下一步勘探方向的决策.采集了研究区共84个泥岩、7个天然气、3个原油样品进行岩石热解、干酪根同位素、生物标志化合物、天然气轻烃与碳同位素等分析,系统对比研究区不同层系烃源岩地化特征,认为松南-宝岛凹陷北部断阶带油气来源于崖城组海相泥岩,以陆源有机质的生烃贡献最大. 结合古环境、古生物与显微组分分析推测崖城组整体为浅海沉积,有利于好烃源岩的形成,在此基础上通过地震相的精细刻画厘清研究区崖城组烃源岩分布特征,结果表明研究区崖城组发育大规模煤系三角洲-浅海相沉积体系,其中前三角洲亚相、浅海相是好烃源岩主要赋存单元,烃源岩沿近凹断阶带分布. 流体包裹体证据表明,松南-宝岛凹陷北部断阶带深水区至少存在两期烃类充注,主要成藏的是晚期高熟煤型气(7.8 Ma之后),证实煤系三角洲-浅海相沉积体系下发育的烃源岩能够为油气成藏提供充足的烃类,晚期更容易大量生成天然气,其东侧的深水区断阶带存在类似的烃源岩分布、热演化特征及输导体系,应是下一步天然气勘探首选.
