| Abstract: | The study on characteristics of gas flow in micro-scale pores is one of important fields in modern mechanics. Results of experiments on saturated gas flow in pores of low-permeability rock were analysed. Laws of gas flow in micro-scale pores were explored. The mechanism of nonlinear gas flow in the low-permeability rock pores was examined. It was found that both gas and liquid flows in micro-scale pores of the low-permeability rock follow the same law. A united model for gas and liquid flows in micro-scale pores of low-permeability rock was established. Results show that there is a good agreement between the model and experiments. The above results can serve as a basis for new theoretical explorations on characteristics of gas flow in micro-scale pores. And they can also serve as a foundation for geological environment preservation and development of underground water resources. |
| Keywords: | low permeability media micro-scale flow mechanism nonlinear flow flow law |
