The Xixia formation in Lower Permian is one of the main segments that contain hydrocarbon source rock. The organic enrichment of carbonate in this formation is not high as a whole in the profile. The average of the total organic carbon (TOC) is only 0.4%. The type of organic matter is main sapropel-type kerogen. The hydrocarbon source rock is in evolution stage of high maturation-over maturation. The organic geochemical analysis of the dense rock samples qurried in profile indicates that: There are 5 organic.
Key words: Nanling-Wuwei; Xixia formation; Hydrocarbon source rock; Evaluation; Scaling.
