Reservoir Dynamic Evaluation And Prediction Of Dingbian Oilfield Fanxue Y9, C4+5, C8

In order to improve the level of employed reserves, slow the current production conflict,and ensure that future oil production increases steadily, as oil exploitation rate reached areasonable level, in this paper, reservoir basic geology and the internal characteristics isrediscovered and fine geological model is established. Based on the analysis of developmentstatus and exploitation characteristics, the main contradiction is finded. Development plan hasbeen adjusted through numerical reservoir simulation of the reservoir.After encryption with24oil wells and8water wells in Chang4+5reservoir, adjustingscheme can increase the liquid producing capacity117.1×104m3, increase oil production45.0×104m3, and improves the extraction about4.7%.After encryption with33oil wells and8water wells in Chang8reservoir, adjusting scheme can increase the liquid producing capacity143.0×104m3, increase oil production18.2×104m3, and improves the extraction about2.1%.After encryption with46oil wells and1water wells in Yan9reservoir, adjusting schemecan increase the liquid producing capacity625.9×104m3, increase oil production60.2×104m3,and improves the extraction about5.0%. It improves the producing degree of reserves andincreases oil recovery.
