Abstract: Based on the onshore oil field development in China，the article investigates the typical composite modes of oil reservoirs in different development period. Targeting at the specific performance of redevelopment of mature oilfields of CNPC，the authors analyze the interrelationship between redevelopment of mature oilfields and tertiary recovery technology deeply, and contribution to EOR respectively at the secondary development period. It is put forward that the composite development mode of secondary and tertiary recovery technology should follow the redevelopment of mature oilfields. The system of redevelopment of mature oilfields is supposed to undertake the double duties, including secondary development and tertiary recovery. With the technological innovations and

efficient conversion of oil development modes，the goal of improving the redevelopment of mature oilfields EOR substantially can be achieved.

Key words:

producing mode, development stage, redevelopment of mature oilfield, tertiary recovery, enhanced oil recovery（EOR）
