Based on measurement of microscopic and fluorescent features of fluid inclusions and their homogenization temperature for 23 reservoir samples from 15 industrial wells at 3 belts in the western slope belt of Dongpu depression, hydrocarbon filling history was determined, in combination with numerical simulation of burial and thermal history of single well.Two phases of hydrocarbon filling existed in the first belt, corresponding to about 10-19Ma and 2-6Ma, respectively.There are two phases of hydrocarbon filling at second belt outside, corresponding to 30Ma and 3Ma, respectively.But, there are three phases of hydrocarbon filling at second belt inside, corresponding to 17-19Ma, 12-16Ma and 2-8Ma, respectively.The time of hydrocarbon filling gradually becomes later from second belt outside, second belt inside to first belt.
Key words: Fluid inclusion; Hydrocarbon accumulation; Reservoir; Dongpu depression.
