Sedimentary Organic Facies Division and Hydrocarbon-Generation Potential of Source Rocks in Coal-Bearing Strata─A Case Study of the Upper Paleozoic in Huanghua Depression, Bohai Basin, China

“…The concept of organic facies was given by Rogers in 1979 for the first time . Since then, more and more attention has been paid to the study of organic facies, and the concept of organic facies has been expanded to sedimentary organic facies, which has rapidly become a new field of petroleum organic geochemistry. − However, different scholars may have different understandings of the concept of organic facies, and their indicators for dividing organic facies may differ greatly. − The origin and development of organic facies are closely related to coal petrology. ,, Therefore, many scholars reveal the characteristics of source rock organic facies from the perspective of coal facies. , Organic facies are classified according to the types of coal-forming marshes, and the indicators for the classification of organic facies focus on the characteristics of coal petrology. , Based on the study of source rocks in the Turpan-Hami Basin and Junggar Basin, Jin divided the organic facies into dry swamp facies, forest swamp facies, flowing water swamp facies, and open water facies and applied them to the resource evaluation of coal-derived hydrocarbon, especially coal-derived oil . Oil and gas geochemists pay more attention to the hydrocarbon-generation potential of source rocks, and the division of organic facies mainly reflects the degree of hydrogen richness and biological source characteristics of organic matter in geological bodies.…”
