Detachable and recyclable three-dimensional visual physical displacement model

The utility model relates to a detachable and recyclable three-dimensional visual physical displacement model which comprises a model body, an upper end cover and simulated wellbores. The model body is of a rectangular cavity structure made of organic glass. An opening is formed in the upper end of the rectangular cavity structure. The simulated wellbores are formed in the mode that capillary steel tubes are matched with plastic pipes. Holes (seams) are formed in the side faces of the capillary steel tubes, intensive irregular micropores are formed in the plastic pipes through stabbing, the portions between the capillary steel tubes and the plastic pipes are filled with silica sand, and the gravel packing sand control technology is simulated, so that the model does not need gluing and avoids a sand flowing phenomenon. A sand filling layer is arranged in the rectangular cavity structure, the detachable and recyclable three-dimensional visual physical displacement model can be filled with silica sand of different grain diameters at different layers to simulate the vertical heterogeneity of a stratum according to the simulated stratum. A silicon gasket with certain viscosity is arranged between the body and the upper end cover to be used as a sealing gasket to guarantee good sealing performance.
