The invention discloses a nozzle for sandblast fracturing. The nozzle for sandblast fracturing comprises a nozzle body and a reinforcing layer arranged on the inner surface of the nozzle body, wherein the reinforcing layer comprises multiple abrasion-resistant layers with different degrees of abrasion resistance, the abrasion-resistant layers include the first ceramic layer which is directly adjacent to the nozzle body, the alloy steel layer which is adjacent to the first ceramic layer and a second ceramic layer which is adjacent to the alloy steel layer, and the abrasion resistance of the second ceramic layer is higher than the abrasion resistance of the alloy steel layer. According to the nozzle for sandblast fracturing, the nozzle can be abraded properly during sandblast perforation, the strength of the nozzle can not be reduced seriously, and the discharge capacity can be improved during fracturing.
