The invention relates to a visual physical simulation experiment method for multi-stage oil filling on carbonate cementation. A highly-visual microscopic seepage glass plate etching device is used, acalcium chloride solution with the concentration of 1 mol/L and a sodium carbonate solution with the concentration of 0.5 mol/L are used for a calcite cementation experiment, and dyed oils of different colors are used for different stages of oil filling experiments. Compared with the prior art, in the method, physical simulation experiments of multi-stage oil filling on carbonate cementation are carried out by means of a microscopic glass plate etching model, experiment phenomena are recorded by means of a microscope and a recording system, and the visuality of the experiment is high; a calcite cementation agent synthesized through the method has the high adhesiveness; and the experiment method achieved by alternatively conducting multi-stage oil filling and multi-stage carbonate cementation accords with the featu
