Instrument parameters and applications for 3D digital core reconstruction.
| Instrument type | Sample size | Instrument resolution | Main application areas |
| Micro CT | Core column scanning (diameter 15-25 mm) | 12-30 μm | Geological description, heterogeneity analysis | Core column scanning (diameter 1-25 mm) | 0.5-12 μm | Fine description, pore network generation | Nano-CT | Less than 1 mm | 65-150 nm | For the scanning of complex structural samples such as shale, microcrystal, tight gas rock, and analysis of pore network | FIB-SEM | Less than 1 mm | 2-150 nm |
