摘要
阐述了煤对气体单分子层吸附与多分子层吸附理论,将煤层对不同气体吸附进行比较,得出煤对不同气体吸附能力强弱,并阐述了注气驱替煤层气作用原理及其优点,从而证明了注气驱替煤层气的可行性。
The gas adsorption theory of monomolecular layer polymolecular layer of coal was presented. Adsorption of coal bed to different gases was compared. Adsorption capacity of coal bed to different gases was acquired. The principle and advantages of displacing coal-bed methane by injecting CO2 and N2 were expounded. It had proven the feasibility of displacing coal-bed methane by injecting CO2 and N2.
