Low-permeability reservoir energy storage and permeability enhancement multi-dimensional parallel experimental device and evaluation method

The invention discloses a low-permeability reservoir energy storage and permeability enhancement multi-dimensional parallel experimental device and an evaluation method. The experimental device comprises a displacement system and a stratum condition simulation system. The stratum condition simulation system comprises a one-dimensional sand filling model, a two-dimensional sand filling model and a three-dimensional sand filling model. The one-dimensional sand filling model simulates gas-liquid seepage of unidirectional flow of the low-permeability reservoir; the two-dimensional sand filling model simulates gas-liquid seepage of plane radial flow of a low-permeability reservoir, and the influence of energy storage and permeability increase on the crude oil extraction effect when a thin reservoir is developed through a horizontal well is studied. The three-dimensional sand filling model simulates the gas-liquid seepage of the spherical surface of the low-permeability reservoir to the centripetal flow, and resear
