| titleOfInvention | Method for testing gas permeability of irregular-shaped loose rock sample |
| abstract | The invention discloses a method for testing gas permeability of an irregular loose rock sample, which comprises the following steps: selecting a rock core from the irregular loose rock sample; then removing the water of the selected core; shaping the core with the water removed and reinforcing the surface strength; then, sealing and additionally installing plugs with through holes at two horizontally opposite positions on the surface of the rock core; manufacturing a casting mould with an opening at the upper end, placing a core with plugs in an inner cavity of the casting mould, and respectively connecting the other ends of the two plugs with air pipes so that the other ends of the two air pipes extend out of the mould; then, casting the inner cavity of the mold by using foam, and forming a complete rock core after the foam is solidified; measuring gas permeability parameters of the prepared complete rock core; finally, the gas permeability and related parameters are determined. The method can efficiently measure the gas permeability of the gas reservoir irregular-shaped loose sandstone, and provides basic parameters for evaluation of similar reservoirs. |
