Abstract: There is controversy about effective source rocks of Triassic Yanchang Formation and oil source of Triassic Yanchang reservoir in Xunyi area,Ordos Basin. To clarify the problem,organic petrology and geochemical analysis were used to analyze the samples of source rocks and oil-gas samples. The results show that the type of kerogen of Chang 7 source rock is mainly type Ⅰand Ⅱ,followed by type Ⅲ,the maturity of organic matter is medium,so it is good source rock. Based on the characteristics of light hydrocarbon,carbon isotope,saturated hydrocarbon gas chromatography and the characteristics of biomarker,it is considered that the oil of Chang 6 and Chang 8 have the similar sedimentary environment and maturity with Chang 7 source rock,they all are mid-mature oil,with fresh water and weak redox environment,and the parent material is with hybrid source based on algae. The Chang 7 source rock has certain contribution for the formation of Chang 6 and Chang 8 reservoirs in Xunyi exploration area.
