Turbine-driven coiled tubing hydraulic oscillator with harmonic reducer

The utility model discloses a turbine-driven coiled tubing hydraulic oscillator with a harmonic reducer, which comprises an outer cylinder, and the outer cylinder is sequentially provided with an upper joint, a bearing set, a turbine set, a universal transmission shaft, the harmonic reducer, a rotary power generator and a fixed power generator from top to bottom. Wherein a plurality of drainage grooves are formed in the inner wall of the upper connector, and a bearing step is assembled on the inner wall of the upper connector; the universal transmission shaft is mounted below the turbine set;the rotary power generator is connected with the harmonic reducer, the rotary power generator is of an eccentric structure, and the end face of the rotary power generator coincides with the end face of the fixed power generator; the overflowing channel of the fixed power generator is of an eccentric structure, the spiral buckling effect generated in the coiled tubing tripping-in process can be effectively solved, the fric
