A hydraulic winch control system with a hydraulic motor oil supplementing function comprises a hydraulic motor for driving a hydraulic winch to rotate, a brake connected with the hydraulic motor, a winch valve group for controlling the hydraulic motor to rotate, and a control valve group connected with the winch valve group. The load-sensitive pump is used for conveying hydraulic oil from an oil tank to the control valve group; the oil supplementing path is used for connecting the control valve group with the hydraulic motor; hydraulic oil is pumped out of the oil tank by the load-sensitive pump, sequentially passes through the control valve group and the winch valve group and then enters the hydraulic motor to drive the hydraulic motor to rotate, so that the lifting of the hydraulic winch is realized; and the oil supplementing path is used for supplementing hydraulic oil in the hydraulic motor and maintaining the stable working pressure of the hydraulic motor. The pressure of the motor in the standby state of the system is maintained by arranging the oil supplementing path, and the unstable condition caused by oil shortage of the motor is avoided.
