The invention provides a water drive reservoir energy consumption-yield-benefit integrated characterization method. The water drive reservoir energy consumption-yield-benefit integrated characterization method comprises the steps of 1, carrying out the oil and gas production system process analysis and node division; 2, calculating the energy efficiency of a water injection system; 3, calculatingthe energy efficiency of an oil extraction system; 4, calculating the energy efficiency of a processing and circulating system; 5, calculating the water-oil conversion efficiency of the oil reservoirsystem; 6, calculating the yield of the whole system; and 7, calculating the benefits of the whole system. The water drive reservoir energy consumption-yield-benefit integrated characterization methodcan predict the yield and benefit under the given energy and cost input conditions, can accurately grasp the working condition of an oil and gas production system by comparing the difference betweenthe theoretical model yield and the actual yield, can analyze a problem link, and provides the improvement suggestions to guide the oil field production.
