| 摘 要： | 对陆相低成熟烃源岩（Ro≤ 0.5 %）有机硫与成烃动力学关系进行了研究。结果表明:①有机硫含量与镜质体反射率（Ro）之间呈负相关关系，即有机硫含量随成熟度提高而减少；②源岩的平均活化能（E）有随有机硫含量增大而减小的趋势；③有机硫含量与源岩活化能分布最小值（Emin）和经可溶有机质抽提后的活化能分布最小值（Emin）之间存在正相关关系；④活化能分布范围Emin～ESEmin（ESEmin＞Emin）内的可溶有机质生烃能力与有机硫含量具有一定的相关性；⑤综上结果推断东营凹陷南斜坡东段沙四段（Es4）源岩中的有机硫在成烃过程中可能起到了一定的作用。

| Abstract: | discuss Relationships of organic sulfur in continental deposit low -mature source rocks and kinetics of py- rolysis hydrocarbon generation have been discussed.These rocks are gathered from Dongying depression in China and their organic matter maturities are not in excess of value Ro= 0.5 %( Ro as vitrinite reflectance). From studied results, we can observe such relationships as follows: ①There is a negative correlation between the organic sulfur contents and values of vitrinite reflectances.② The higher organic sulfur contents in these source rocks, the lower average activation energies of these rocks.③There is a positive correlation between or- ganic sulfur content and the least value( Emin)of activation energy distribution or the value (ESEmin)of activation energy distribution after soluable organic matter are extracted from these rocks. ④Soluable organic matter dis- tributing in the activation energy distributive intervals Emin,ESEmin] ( Emin < ESEmin) not only has hydrocarbons generation ability, but also there is a certain correlation trend between the yield of accumulating hydrocarbon and the sulfur content.⑤Putting all above aspects together, authors point out organic sulfur in low -mature Shasi(Es4)source rocks of Dongying depression maybe havea certain act on the course of hydrocarbon genera- tion in the study area. |
