The utility model discloses a heterogeneous body sandpack column that is used for research of heterogeneous body oil reservoir seepage flow characteristic, it includes the cuboid casing, a side material of cuboid casing is clear glass, the parallel direction of lateral wall along two arbitrary relative settings with the casing in the cuboid casing is provided with two foraminiferous baffles so that separate equidistant three space in the casing, block respectively in the recess of reserving in the casing wall so that two foraminiferous baffles can or be pulled out along the recess propulsion at the both ends of two foraminiferous baffles, the baffle is used for filling out the quartz sand of different mesh numbers in the equidistant three space that goes out, both ends are fixed with the blind flange respectively about the casing, a wellhole and three wellhole have been opened respectively on the blind flange of cuboid casing both ends, install a plurality of pressure sensor on the cuboid casing. This device can be used to realize three -layer heterogeneous body physical model.
