Method for differentiating economic recoverable reserves from newly found proven reserves is established. Economic conversion degree of newly found proven reserves and economic recoverable reserves are calculated based on air-permeability of reservoirs and on establishing the relational expression and chart between economic conversion degree of geologic reserves in developed oilfield and air-permeability of oil reservoir. This method is easy to obtain parameters and to calculate, and it has important significance on calculating the economic recoverable reserves in the newly found proven reserves quickly and accurately.
