Abstract: Considering the ability of oil reservoir with polymer flooding project in China,the effects of oil-displacement parameters on the distance between water injecting well and production well,polymer dosage,oil price and aggregate investments of drilling,surface construction and chemical agent in different reservoir were analyzed.On the basis of the balance principle,the aggregate investment can be reduced to the needed increasing oil production under the standard oil price.Then,the limit of needed enhanced oil recovery can be obtained.A technical and economic evaluation model was established on the reservoir adaptability of polymer flooding technology.The polymer dosage was also optimized by the indexes of recovery factor and oil production per ton polymer was raised.This method is simple and credible for evaluating the development plan of polymer flooding project.

Key words: onshore oilfield, polymer flooding technology, technical and economic evaluation model, recovery factor index, polymer dosage
