Abstract:The aim of the study was to elucidate the impact of different moisture phases during gas injection on coalbed methane displacement. The coal samples were treated with two methods: water vapor adsorption and liquid water stirring. The differences in the coal samples treated with various moisture phases during gas injection for coalbed methane displacement were investigated by using the isothermal adsorption curves of CH 4 , N 2 , and H 2 O in coal and N 2 displacement of CH 4 in coal. The results indicate that … Show more
