The invention relates to an energy-saving electric drilling winch and an energy feedback method thereof. The energy-saving electric drilling winch comprises a power generation integrated motor, an energy storage power supply, an inverter, a connecting device and a winch body. The power output end of the energy storage power supply is connected with the power input end of the power generation integrated motor through the inverter, the power input end of the power generation integrated motor is further connected with a well site power supply, and a power output shaft of the power generation integrated motor is connected with the winch body through the connecting device. The energy-saving electric drilling winch driven by the power generation integrated motor is adopted, the drilling winch isdriven by the energy storage power supply and the well site power supply in a time-sharing manner, the structure is simple, and convenience of maintenance is guaranteed; and the performance is equivalent to that of a conventionally-driven electric drilling winch. Repeated utilization of electric energy is achieved, and the total energy cost of well drilling construction is greatly reduced. The winch is suitable for being popularized in exploration drilling equipment, the winch device comprises a geological drilling rig, a petroleum drilling rig and a water well drilling rig, and economic effects are remarkable.
