Method and equipment for predicting critical liquid-carrying gas production rate of shale gas reservoir horizontal well

The embodiment of the invention provides a method and equipment for predicting the critical liquid-carrying gas production rate of a shale gas reservoir horizontal well. The method comprises the steps: obtaining a pressure field and natural gas components along a shale gas reservoir horizontal well shaft; obtaining a natural gas quasi-critical pressure and a quasi-critical temperature according tothe natural gas components and the pressure field; and obtaining a natural gas deviation coefficient according to the natural gas quasi-critical pressure and the quasi-critical temperature, and predicting the shale gas reservoir horizontal well critical liquid-carrying gas production rate according to the natural gas deviation coefficient. According to the method and equipment for predicting thecritical liquid-carrying gas production rate of a shale gas reservoir horizontal well, the deviation coefficient of natural gas is obtained by obtaining the pressure field along the shaft of the shalegas reservoir horizontal w
