A helical shunt nipple for gas drilling relates to the manufacturing technical field of petroleum and gas drilling tool nipple, satisfying both the debris-carrying requirement and the air flow speed of the drill lever and the drill stem; the nipple comprises a shunt nipple body and shunt holes; the shunt nipple body has a hollow cylindrical structure and lengthened shunt holes are arranged from top to bottom on the shunt nipple body; the utility model solves the problem that when the air flow of the screw drilling tool exceeds the specified working air flow, the rotation speed of the screw rotor is too high and the rotor speed is out of control; the utility model can generate high-speed helical flow, reinforce air flow debris-carrying capacity, solve the inconsistence of the horizontal drilling debris-carrying required air flow and the air screw specified air flow, improve the gas drilling efficiency.
