The results show that there are six types of reservoirs. There are five Hydrocarbon accumulation models. Hydrocarbon accumulation models controlling over hydrocarbon distribution are showed in reverse fault tilting uplift in source area, uplift in low-lying area and lithology traps in low-lying area are favorable areas of Nanyi Member, Tongbomiao Group and part of Naner Member. Reverse tectonic connected by long-time fault is favorable area for hydrocarbon accumulation of Damoguaihe Group and Naner Member; paleo-uplift laterally connected with source rock of Nanyi Member is the favorable area for hydrocarbon accumulation of bedrock buried hills.ml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
