Abstract

Daqing oilfield has entered the water cut rising stage of late polymer flooding, it is necessary for injection well to take measures of separate injection. With the increasing reduction of the main reservoir recoverable reserves, polymer flooding of the Class reservoirs is an important replacement method to oil development, which has an important meaning to develop reasonable and efficient. However, due to the complexity of the geological conditions of the Class reservoirs, the difficulty of selecting separate injection wells and layers is relatively large. According to the geological characteristics of the Class reservoirs, the technical limits of layering polymer injection in the Class reservoirs are studied by numerical simulation, which can provide scientific basis for the oilfield development decision.
