Based on primary screening and classification of hydrocarbon resources, fault block group division and selection of typical unit, the prediction and economic evaluation of the chemical flooding potential in Shengli petroliferous area has been carried out by numerical simulation. The study shows that 125 units are fit for polymer flooding with OOIP of 92903×10 4t, and increment of recoverable reserves 7887×10 4t. Among these units, 24 may be operated in the near future, with OOIP of 39256×10 4t, and incremental recoverable reserves of 3902×10 4t. 18 units suit for ASP flooding, with OOIP of 14746×10 4t, and recoverable reserves increment of 2710×10 4t. The economic potential of polymer flooding and ASP flooding is 3319×10 4t and 2710×10 4t respectively at present technical conditions.
