A method for manufacturing a fine physical model of a target oil area of a fracture-vug type oil and gas reservoir organically combines a CT scanning technology, a three-dimensional seismic imaging technology and a 3D printing technology, and establishes a single fracture image library and a single hole image library. Selecting proper monomer crack images and/or monomer hole images to permutation and combination in 3D image editing software to obtain a target oil region simulation image which is the same as the three-dimensional seismic model obtained by the three-dimensional seismic imaging technology; a fine physical model capable of covering the whole target oil area and even the whole area underground stratum of the fracture-vug type oil and gas reservoir is printed through a 3D printer, the fine physical model is wide in coverage and can reflect the real aperture structure in the underground stratum of the area, various indoor displacement experiments are carried out on the model, and the model can be us
