| description | The invention discloses an axial gas seepage test system under a multi-field coupling condition, which comprises a main body model, a methane gas cylinder, a gas booster pump, a gas storage tank, a pressure reducing valve and a gas pressure gauge are sequentially connected to a gas inlet pipeline of the main body model, and a gas-liquid separator, a dryer and a gas flowmeter are sequentially connected to a gas outlet pipeline on the right side of the main body model. Four fluid injection channels are arranged at the bottom of a box body of the main body model, and each fluid injection channel is provided with a set of outlet flow meters with the measuring ranges of 500ml/min, 5000ml/min and 30L/min for selective installation so as to record outlet flows of different orders of magnitude, and then permeability is analyzed. Gas is fed into the lower part, and multi-point seepage is realized through a multi-fluid injection channel; by adopting the structural combination of the anti-fluid channeling plate, the bre |
