The invention discloses a gas nozzle structure of a gas turbine, and relates to the technical field of gas turbines.The gas nozzle structure comprises a throat pipe mechanism and a throat nozzle mechanism, the throat pipe mechanism comprises a throat pipe body, and a mounting bin is fixedly mounted at the top of the throat pipe body. The connecting pipe opening is used for being connected with fuel injection equipment, fuel firstly passes through the throat pipe body and then is injected forwards when being injected out, at the moment, the surface of the dispersion hemisphere is hemispherical, the fuel is effectively dispersed to the periphery, and then the fuel is sprayed out through multiple holes of the first discharging openings, the second discharging openings and the third discharging openings and is more uniform; the first discharging port, the second discharging port and the third discharging port are all inclined holes, and through multi-angle, multi-direction and multi-range injection, fuel is fully
