At present, Daqing Oilfield has entered the stage of high water cut, high difficulty and high cost development. The polymer injection blocks of the main oil layers are gradually reduced, and the reserve potential of the oilfield is obviously insufficient, and the potential of stable production replacement is reduced. Therefore, the polymer flooding development of the second type of oil layers has become one of the main ways to replace the production capacity of the oilfield, which is an important guarantee for the sustainable development of the oilfield. The optimization degree of oil displacement scheme for Class II reservoir directly affects the ultimate recovery of polymer flooding. Therefore, according to the development characteristics of Class II reservoir in Block A of Sazhong Development Zone, this paper carries out the optimization design of polymer flooding scheme based on different parameter design methods, laboratory experimental research results and mature experience of other Class II reservoir blocks that have been injected.
