Multidirectional multilayer full-diameter fracture core seepage simulation device and application thereof

The invention discloses a multidirectional multilayer full-diameter fracture core seepage simulation device and application thereof. The seepage simulation device comprises a full-diameter crack core clamping module, a radial multidirectional multilayer seepage injection and production module and an axial seepage injection and production module. According to the simulation device, rock core seepage can be simulated from multiple directions and multiple angles such as the axial direction, the radial direction and the complex multiple directions, the simulated fluid seepage behavior is closer to the actual condition of an oil reservoir, and secondary damage and operation inconvenience caused by drilling a rock sample from a full-diameter rock core are avoided. The device has high reference value for researching the seepage law of the complex hydraulic fracture of the compact oil and gas reservoir. According to the simulation device, comprehensive radial seepage simulation can be conducted on a full-diameter fra
