An intelligent water invasion tracking and early warning method for water-gas reservoirs includes based on the gas-water two-phase seepage equation, obtaining the water invasion constant and the water flooding index by combining the gas-water two-phase permeability expression with the water invasion material balance method, fitting by automatic fitting method, finding a best fitting between an optimal theoretical value and an actual value, dividing a block into different water invasion areas based on the water flooding index, revising a water invasion classification boundary based on production dynamic monitoring and well logging interpretation results, and tracking and early warning water invasion by drawing a water flooding index distribution map of water-gas reservoirs according to the water flooding index. The present invention solves the problem of no method for tracking and predicting the water invasion direction and the water invasion intensity in real time.
