Organic Geochemical Feature of Triassic Hydrocarbon Source Rock and the Oil Source Researches in Yichuan Sag

  • Yichuan sag is a cenozoic sag and located in thesouthern edge of North China Basin. The TanzhuangFormation and Chunshuyao Formation of Upper Triassicin the sag are main source beds and oil source qualitiesare good.The main organic matter is kerogen Ⅲ,and thethermal evo1ution is in low-mature period.Early Yanshanis main oil generative period.Crude oil is characterized byproximal short distance migration.
