Study on Layer Combination Limits of Reservoirs for polymer flooding

摘要：

　　Heterogeneity of reservoir may affect the development of oil production obviously.Polymer flooding could improve the passive effect.There were some experiments and numerical calculations finished to research the relationship between permeability ratio and recovery.The layers combination limits for polymer flooding could be obtained.Some analyses about layer combination limits have been done.The layer combination limits was the permeability ratio 5-8.When permeability ratio was more than this range,the effect of polymer flooding could be bad.The decreased recovery in low permeability layers would reduce the total recovery obviously.
