Laws of gas and water flow and mechanism of reservoir drying in tight sandstone gas reservoirs

Natural Gas Industry B, 2021
The reservoir permeability of tight sandstone gas reservoirs is low, which makes it difficult to carry out displacement flow experiments on real cores underground conditions, so the microscopic flow mechanism can be hardly studied.
