| Abstract: | The thermal decomposition experiment,microscopic composition analysis,element analysis,vitrinite reflectance and biomarkers were utilized to comparatively analyze and contrast the organic geochemical characters of source rocks of Liushagang Formation,Wushi Sag based on its abundance,types,maturity and sedimentary environment.The results show that the oil shale in bottom of L2 has the highest organic content,which belongs to typeⅠ-Ⅱ1 kerogen.The organic matter are in the mature stage,which is the most favorable source rocks of the study area,followed by oil shale on top of L2,normal source rocks of L2 and L3 are evaluated as good source rocks,the L1 source rock are evaluated as medium source rocks.It is also found that Liushagang Formation belongs to weak reduction-reduction environment.Apart that the organic source material of L1 is mainly higher plant,the organic source material is lower aquatic plants mixed with some higher plants,and especially the bottom of L2 has more algae input. |
| Keywords: | Wushi Sag source rock biomarker geochemical characteristic |
