Based on the preliminary screening and classification of resources, the classification and evaluation, the division of block groups and the selection of typical units, the chemical potential of Shengli oilfield is predicted by numerical simulation and the economic evaluation is carried out. The results show that there are 125 units suitable for polymer flooding with a geological reserve of 92 90 3 × 10 4 t, an increase of recoverable reserves of 7887 × 10 4 t, of which 24 units can be practiced in the near future with a geological reserve of 392 56 × 10 4 t, recoverable reserves can be increased 390 2 × 1 0 4t; suitable for ASP flooding unit 18, the geological reserves 14746 × 104t, can increase the recoverable reserves 2 71 0 × 1 0 4t. Under the current technical and economic conditions, recoverable reserves increased by polymer flooding and ASP flooding are 331 9 × 104t and 2 710 × 104t, respectively
