Recently, newreservoirs have been found in Chang 9 and Chang 10 oil reservoir set of Triassic Yanchang Formation in Yingwang area, Ordos Basin. Based on source rocks characteristics, oil-source correlation and accumulation patterns, it is considered that even though the source rocks of Chang 9 oil reservoir set is a set of good source rocks, it contributed little to the hydrocarbon accumulation of Chang 9 and Chang 10 oil reservoir set. The oil in Chang 9 and Chang 10 oil reservoir set in Yingwang area are mainly from the source rocks of Chang 7 oil reservoir set in Huachi-Taibai-Zhengning-Yingwang area. Abnormal high pressures produced during the diagenetic evolution are the main force for hydrocarbon migration. Pores and fractures are the main migrating system, which allows oil tomigrate vertically along fractures and inject laterallywhen it met sandstone.
