The invention provides a method for optimizing the online real-time foaming agent adding amount of foam drainage gas recovery of a gas well. The method comprises the steps: acquiring the production dynamic data of a target gas well in real time; respectively determining the liquid accumulation amount Qwt in the oil pipe and the liquid accumulation amount Qwc in the oil jacket annulus according tothe production dynamic data in combination with wellbore data, and determining the liquid accumulation amount Qtotal in a gas well wellbore; according to the liquid accumulation amount Qtotal in the shaft of the gas well, the daily water production Qw in the production dynamic data, the recommended use volume concentration n of the foaming agent and the ground recommended dilution ratio 1: f, determining the real-time optimal injection amount Q of the foaming agent of the target gas well for injection of the foaming agent, thereby achieving the optimization of the online real-time foaming agent adding amount of gas we
