高邮凹陷沙埝地区烃原岩生物标志物研究

Biological marker characteristics in Shannian of Gaoyou depression

利用先进的流体包裹体分析技术,从分子地球化学的角度深入剖析烃类包裹体地球化学信息,通过对高邮凹陷沙埝地区烃原岩进行GC-MS、GC-MS-MS检测,探讨了油气形成和演化阶段及其勘探潜力,认为本地区原始母源输入中具有低等水生藻类和高等植物蜡质的双重贡献,但以高等植物蜡质在生源组成中略占优势,热演化程度不高,为低成熟-成熟原油。

Utilize advanced fluid parcel body analyse technology,we deeply analyze hydrocarbon parcel body geochemistry message in terms of molecule geochemistry. The original sources in Shanian of Gaoyou Depression are ditected by GC-MS and GC-MS-MS techniques. Low maturation and maturation oils matter of current part forms from low grade aquatic alga and higher plant wax double contribution, but the later is advantage. So we probe into hydrocarbon form and stage of evolving and explore potentiality.
