Abstract: The huge reserves of oil shale were detected long time ago at the northern foot of the Bogeda Mountain, but unfortunately, their research degree is relatively low. The oil shale occurs in Upper Permian Lucaogou Formation formatted in the highstand systems tract (HST) of deeplake facies, and belongs to the oil shale of low oilgenerating ratio and high volatilization. Based on data of organic element analysis and pyrolysis analysis, the genetic type of the oil shale are classified into mainly sapropelic type (I type) and humussaproptlic type (II₁ type) by the crossplot method. In the Later Permian period, the Sangonghe was the depositional center of the area. The Sangonghe area is believed to be the most favorable sites for further exploitation and development for huge reserves，high oil yield and simple exploiting conditions anticipated.
