The invention discloses a heating method of a heat storage intermittent reheating furnace during oil shale retort oil refining. During the oil shale retort oil refining, cycling gas heated by four heat storage intermittent heating furnaces serves as a gas heat carrier and is fed into a gas retort so as to perform alternate heat supply to the gas retort, wherein lattice bricks in a heat storage chamber of the heating furnace are heated by using two heating furnaces; the cycling gas is introduced into another two heating furnaces, the gas and the lattice bricks in the heat storage chamber are introduced into the gas retort so as to form a heat cycle, the cycling gas is heated by the heating furnaces and is introduced into the gas retort to be subjected to alternate heat cycle switching, and the heat cycle is switched every two hours. The method has the advantages that the heat supply is stable, the service life is long, the heat value of the gas generated by the gas retort is high, and the condition that the heating furnaces are difficult to ignite is avoided.
