Study on multi-application of CO2 injection into coal bed

  • 摘要: 为了减轻环境污染,提高煤层气产率,增加能源储备,根据煤层气地质学和生物气的基本理论,提出二氧化碳(CO2)注入煤层多种用途这一新观点。研究结果显示:煤对CO2具有很强的吸附能力,可将煤层作为CO2的储集层;煤具有优先吸附CO2而滞后吸附甲烷(CH4)的特性,向煤层注入CO2可大大提高煤层气的采收率;产甲烷菌具有利用CO2生成CH4的能力,新生成的CH4成为能源储备的有益补充。可见,CO2注入煤层不仅可有效减少温室气体的排放,强化煤层甲烷产出,而且为新能源生物CH4的生成提供了基质。
    Abstract: In order to reduce environment pollution,improve coalbed methane recovery and increase energy re-serve,this paper based on the principles of coalbed methane geology and biogenic gas,proposed a new viewpoint of multi-application of CO2 injection into coal bed.The studied results show that coal beds can be used as CO2 res-ervoirs because coal has strong adsorption capacity for CO2;and CO2 injection into coal beds can improve coalbed methane recovery because coal is preference for CO2 adsorption and postponement for methane(CH4) adsorption;and CH4,which is a new energy generated by methanogens from CO2,is the beneficial complement of the energy.It is obvious that CO2 injection into coal beds can not only reduce the green-house gas emission and improve coalbed methane recovery,but also provide the basic material to new energy:biogenic methane.
