Two-dimensional quantitative-squeezing visible physical simulation device for petroleum migration and accumulation

The utility model provides a two-dimensional (2D) quantitative-squeezing visible physical simulation device for petroleum migration and accumulation, comprising a model body for filling a 2D geological model, a cover plate and a pressure plate with a piston. The pressure plate is made of transparent glass and provided with the support surface for supporting the 2D geological model, the 2D geological model is arranged between the cover plate and the pressure plate with the piston, the 2D geological model is squeezed to the cover plate by the pressure plate with the piston. The 2D geological model is compacted by the piston, thus the 2D geological model over is prevented from being excessively compacted to break visible cover and lead to damage to instruments; insufficient compacting of the 2D geological model is prevented from causing visible deformation or collapse leading to damage to the instruments; insufficient compacting of the 2D geological model is prevented from causing invisible deformation or collap
