Summary:The invention discloses an intrinsically safe method for exhausting oil gas of an oil storage tank, relates to cleaning construction operation of the oil storage tank and comprises the following steps: firstly carrying out oil gas replacement on an oil tank by using low-temperature inert gas to inert the oil tank space so as to form an inexplosive condition; and adopting high-temperature inert gas to accelerate the evaporation and discharge of oil gas so as to realize that the concentration of the oil gas in the oil tank can be reduced in a safe range.
