辽河盆地宋家洼陷中生界油藏地球化学特征及油源对比

Geochemical characteristics and oil & source rock correlation of Mesozoic reservoir of Songjia depression,Liaohe basin

  • 摘要: 总结了辽河盆地宋家洼陷中生界油砂和烃源岩的地球化学特征,根据油砂饱和烃气相色谱特征和生物标志物特征等,进行了油源对比。研究表明,宋家洼陷有机质的热演化处于未成熟-低成熟阶段,九佛堂组为本区的主力烃源岩。阜新组7个油砂样品按成因分为两类,低伽马蜡烷型油砂与九佛堂组烃源岩生标指纹特征类似,两者有成因联系,高伽马蜡烷型油砂未找到与之匹配的油源岩。

     

    Abstract: Geochemical characteristics of oil sands and source rocks of Songjia depression,Liaohe basin,are summarized.Oil and source correlations are performed by applying the char- acteristics of vapor-phase chromatography of saturated hy- drocarbon and biological markers in the oil sands.Study shows that the thermal evolution of organic matters is in the immature to low mature stage,and Jiufotang Formation pro- vides main source rocks.7 oil sand samples in Fuxin Forma- tion can be classified as two types according to the genesis. The low-gammacerane oil sand has genetic relationship with the source rocks of Jiufotang Formation because of the similar characteristics of biological marker,while the high gammacerane oil sand fails to be found its matching source rocks in the depression.
