Laboratory Study of the Displacement Coalbed CH4 Process and Efficiency of CO2 and N2 Injection
ECBM displacement experiments are a direct way to observe the gas displacement process and efficiency by inspecting the produced gas composition and flow rate. We conducted two sets of ECBM experiments by injecting N2 and CO2 through four large parallel specimens (300×50×50 mm coal briquette). N2 or...
