Abstract: The migration and accumulation of hydrocarbons can be divided into three stages (1) the mature crude oil of the Indo-China movement stage; (2) high-mature to condensate oil of the Yanshan movement to the Himalayan movement stage; (3) pyrolysis of liquid hydrocarbons and methane gas of Himalayan movement stage by studies on the types, attitude and distribution in the cement and filling of the Carboniferous reservoir bed. According to the character of the composition of hydrocarbon inclusions and distribution of the reservoir bitumen, the studied area has three regional zones with different history of migration, accumulation and maturity, which are the Kaijiang-Zhongxian-Chongqin region, Daxian-Guangan region and Wanxian-Yunyiang region.
