摘要：

Gas mixture, consisting mainly of N-2 and a small amount of CO2, enhanced coalbed methane recovery (G-ECBM) technology is a way to enhance low permeability coals' methane recovery, by taking advantage of the permeability-enhancing role of N-2. Two different scale pilot filed tests of G-ECBM have been carried out in Pingdingshan Coal Mine and in Lu'an Coal Mine. The two pilot tests were all conducted in underground tunnel. Tests results showed that, compared with existing conventional extraction method, G-ECBM technology had great breakthrough in principle and effect, and was technically feasible; gas injection had effects on not only the neighbouring production wells but also the a-little-far production wells; gas injection enhanced the concentration and flow rate of coalbed methane.
