The Chang 9 oil reservoir set in Jiyuan Oilfield is a favorable layer to replace for rolling exploration, and there are obvious differences on oil reservoir conditions and enrichment degree in different areas. Based on core observation, logging interpretation, sample testing and related simulation experiments, from hydrocarbon kitchen, the channel between the reservoir and the distance, dynamic, this paper compared and analyzed the hydrocarbon accumulation differences of Chang 9 oil reservoir set in Hongjingzi, Hujianshan and Luopangyuan areas. The results show that Hongjingzi area is near the hydrocarbon source rocks, reservoir properties are also good, source reservoir pressure is strong, so this area is favorable for hydrocarbon enrichment; Hujianshan area has good reservoir properties, but it is relatively distant from the hydrocarbon kitchen, and the source reservoir pressure is small, so hydrocarbon enrichment degree is general; in Luopangyuan area, source reservoir pressure is small, fracture was not developd, and reservoir properties are poor, so hydrocarbon enrichment degree is poor.
