As a result , the physical property , sulfur content and bulk composition of crude oils in this area vary significantly
因此，在整体上，这两个地区原油物性、含硫量和族组成变化很大。
This study used some techniques such as organic geochemistry bulk composition combined with molecular geochemistry , source rock analysis and evaluation of organic petrology , carbon isotopes of organic matter , petroleum geology inference etc . the emphasis is mainly concentrated on the source rocks belong to the shahejie formation of pal eocene , including the source rock evaluation of denan region , geochemistry of the source rock , biomarkers of immature oils and source rocks . then the ancient geological environment was established and immature oil formation mechanism was proposed . following results have been tentatively proposed in this thesis : 1 ) based on the organic petrology studies , most of source rocks in this region is belong to immature source rock
本项研究以德南洼陷重点烃源岩- - -下第三系沙河街组为对象，应用有机地球化学理论与方法对其有机质类型和丰度、成熟度、生烃潜量等进行研究；通过特征生物标志化合物的分析，阐明研究区未熟-低熟烃源岩母质构成、沉积环境和成熟演化；通过油源对比和生烃条件综合分析，提出本区烃源岩生烃机制，建立未熟-低熟烃源岩有机质生烃模式。
