Permeability distribution is an important information parameter in reservoir exploitation. By analyses, an analytical model has been established by using well test data to determine the reservoir permeability distribution. By the model, formation permeability distribution can be determined for the single phase flow. By inducting deviation factor, an influence of water cut to the determination of reservoir permeability distribution has been considered, so that the determination of reservoir permeability distribution becomes more exact and reliable.<
