The drilling process is divided into several major procedures, including lifting and lowering the wellhead, drilling, mud circulation, tool replacement, casing installation, and logging. Mainly divided into winches, turntables, and mud pumps. The winch consists of a drum, gearbox, clutch, brake, motor, and control equipment. Used for lifting and lowering derricks, lifting and lowering drill pipes and casings. As the well depth increases, the drilling tools become longer and the weight rapidly increases, and the load on the winch also increases. There are currently 7000m deep oil wells in China, with drilling tools weighing nearly 600t. Due to the need to lift and lower the drill pipe once every 9m of drilling, the proportion of winch operation time increases with the increase of well depth. To reduce costs, it is hoped that the working time in the field or at sea will be as short as possible, which not only requires the winch to operate at high speed. Smooth start stop is required to ensure that the drilling equipment is not damaged and to improve the quality of the well, and the driving equipment also needs to have good dynamic characteristics. If working in the inner well area. The power supply can be connected to the well area power grid. When lowering the drill pipe, the motor works in a generating state, and the energy can be fed back to the power grid, resulting in significant energy-saving effects
