The utility model relates to a radial exhaust orifice extension structure in a screw compressor. The exhaust pressure drop of an existing screw compressor is large, and the performance of the compressor is affected. A first radial exhaust orifice and a second radial exhaust orifice are formed in a rotor cavity, and the compressor is characterized in that a first radial exhaust orifice extending runner and a second radial exhaust orifice extending runner are arranged on a compressor shell, and the first radial exhaust orifice extending runner is composed of a first wall face and a first bottom face; the second radial exhaust hole extending flow channel is composed of a second wall face and a second bottom face. One end of the first wall face is located on the end face of the compressor shell, and the other end of the first wall face communicates with the first radial exhaust hole. One end of the second wall face is located on the end face of the compressor shell, the other end of the second wall face is commun
