The invention discloses a well temperature forecasting method for a horizontal production well in a fire flooding process. The method comprises the following steps of: constructing an oil release section infinitesimal body temperature forecasting model and a non oil release section infinitesimal body temperature forecasting model according to an infinitesimal body heat balance condition in a well section of the horizontal production well; constructing a horizontal production well temperature forecasting model according to a boundary condition of the well section of the horizontal production well, the oil release section infinitesimal body temperature forecasting model and the non oil release section infinitesimal body temperature forecasting model; and generating a horizontal production well temperature forecasting result according to input oil layer parameters of the horizontal production well in an oil layer fire flooding process, well barrel data and fluid data as well as the constructed horizontal production well temperature forecasting model.
