According to some geological and geochemical data of well Sutan 1 of depth from 2 536.5m to 2 697.0m,including the homogenization temperature of fluid inclusion and the geochemical characteristics of crude oil,the hydrocarbon accumulation history of the studied region was analyzed.The result shows that the crude oil has the properties of high evolution degree with well Sutan 1.The precursor type is mainly high terrestrial plants.Among them three crude oils from depth of 2 620.67m,3 640.57m and 2 697m have been charged with crude oil with aquatic organism.And the crude oil has deposited in weak oxidizing to oxidizing environment with fresh to slight saline water,which is better for preservation and transformation of organics.The characteristics of fluid inclusion with well Sutan 1 show that there are at least three times of filling of oil and one time of filling of gas.And two periods of petroleum accumulation existed in the crude oil of well Sutan 1.The reservoir forming time of the first charge with oil is about 142Ma.The reservoir forming time of the second charge with oil is about 107Ma,which is tectonic inversion of the Yanshanian orogenic movement in Late-Early Cretaceous.
