The method of gas storage predictive interaction zone of gas and water well productivity and means

The present invention discloses a method and apparatus for forecasting gas storage gas-water interaction zone well productivity, wherein the method comprises: determining a function of the amount of invasion purification gas reservoir pressure, determined in accordance with the operation of gas storage reconstruction function process gas and water wells in the study of the interaction zone; gas reservoirs or well test data processing data of said subject well, gas well binomial equation to determine the interaction of water reduced air displacement capacity factors; in accordance with the said air-water displacement factors interact to reduce capacity, gas flow STORAGES experimental design process, a test gas storage life of each cycle period vapor permeability changes; percolation correction results can binomial gas equation, deducting said subject gas storage wells during gas operation due to the interaction of water displacement capability seepage loss capacity. The present invention can improve the accuracy of the gas reservoir flooding the converted gas storage well productivity prediction.
