| 英文摘要 | In this work, a multi-scale pore network with fractures is developed against experimental data in a wide range of degrees of water saturation. The pore network is constructed based on the measured micro-structure information at several length scales. The gas transport is predicted by different gas transport equations (e.g. Javadpour, dusty gas model (DGM), Civan and Klinkenberg), which can consider the fundamental physics mechanisms in tight porous media, such as Knudsen diffusion and viscous flow. Then, the model is applied to simulating the gas permeability of the Callovo-Oxfordian (COx) claystone. The predicted gas permeability is basically in good agreement with the experimental data under different degrees of water saturation. Then the effects of micro-fissures are studied. The results suggest that this model can predict the gas flow in other tight porous media as well and can be applied to other fields such as carbon capture and storage.
