The invention discloses a petroleum drilling machine winch position control system and method. The system comprises a PLC, a human-computer interface, a winch motor, a winch encoder and a winch frequency converter. The output end of the human-computer interface is connected with the input end of the PLC; the output end of the PLC is connected with the input end of the winch frequency converter; the output end of the winch frequency converter is connected with the winch motor; the winch motor and the winch encoder are respectively arranged on the winch; the output end of the winch encoder is connected with the PLC, and the position of the winch is fed back to the PLC. In the operation process of the winch, acceleration and deceleration are stable, and a set position is accurately reached. The device saves energy, reduces equipment loss, achieves standardization of repetitive drilling activities, reduces influences of human factors such as driller personal experience level on drilling operation, guarantees consistency of repetitive operation, and improves drilling operation quality and efficiency.
