Visual experiment device and method for simulated cross fracture seepage

The invention discloses a visual experiment device and method for simulated cross fracture seepage. The visual experiment device comprises a cross fracture mold and a test device for observing cross fracture seepage. The inside of the cross fracture mold is of a T-shaped cross fracture structure; and the test device comprises a fixed device, a flow control device and a data acquisition device. Thetest device realizes a quantitative observation research on a transparent cross fracture seepage process by using a light transmission principle; and meanwhile, flexible adjustment of relative positions of a camera, a light source and the fracture mold is realized on a mechanical structure, so that three-dimensional real-time observation of the cross fracture seepage process is realized.
