Unconformity screened oil-gas reservoir physical simulation experimental device and method

The invention relates to an unconformity screened oil-gas reservoir physical simulation experimental device and method. The experimental device comprises a stratigraphic oil-gas reservoir simulator, wherein the stratigraphic oil-gas reservoir simulator comprises a stratigraphic box body and a unconformity cabin located above the stratigraphic box body; a fault zone box body is connected to the side surfaces of the stratigraphic box body and the unconformity cabin; an oil filling hole and an oil discharging hole on the fault zone box body are respectively connected with a fluid injection system and a fluid output system; holes are formed in the side, connected with the stratigraphic box body and the unconformity cabin, of the fault zone box body and the baseplate of the unconformity cabin; and the stratigraphic box body comprises a plurality of layers of independent simulation rooms, the lengths of the simulation rooms at the upper layers are smaller than those of the simulation rooms at the lower layers, all the simulation rooms are in contact connection with the unconformity cabin, and holes are formed in two side surfaces of each layer of simulation room. The unconformity screened oil-gas reservoir physical simulation experimental device and method can simulate the oil-gas migration and accumulation process under screening of an unconformity surface, analyze the stratigraphic unconformity screened oil-gas reservoir forming mechanism and control factors, and deepen the recognition of both stratigraphic oil-gas reservoir forming factors and oil-gas distribution rules, thereby providing references for oil-gas exploration in petroliferous basins and well serving experimental teaching.
