To obtain a suitable tong's chart for ultra-low permeability reservoir is an important means to evaluate its development effect. Based on the classification of ultra-low permeability reservoir blocks, this paper revises the standard Tong's curve proportion coefficient of various blocks, and draws charts of ultra-low permeability reservoir including theoretical Tong's chart, the theory chart of water cut rise rate and water cut, the theory chart of water storage rate and water cut, and predicts the recovery rate and water injection development effect of various blocks evaluation. The results show that the theoretical charts drawn by the modified proportional coefficient offers a more accurate recovery prediction and evaluation on waterflooding effect evaluation of ultra-low permeability reservoir block.
