摘要
scCO_(2)强化煤层气开采技术因其具有节能减排和高效开采煤层气的特点,已成为未来煤层气开采和发展的新方向。经室内试验和现场实践证明,scCO_(2)-ECBM技术可以显著提升煤层气的产量,对残余CO_(2)实施就地封存,减少碳的排放。介绍了scCO_(2)的特性,简述了scCO_(2)开发煤层气的相关机理,着重论述了scCO_(2)-ECBM工艺的关键技术,分析了scCO_(2)强化开采煤层气的研究现状,并指出了实现煤岩储层中CO_(2)地质封存与煤层气开采的规模高效科学环保一体化是强化开发煤层气下一阶段的发展目标。
The scCO_(2) enhanced CBM recovery technology has become a new direction for CBM recovery and development in the future because of its characteristics of energy saving, emission reduction and efficient recovery of CBM. Laboratory tests and field practices have proved that the scCO_(2)-ECBM technology can significantly increase the production of coal-bed methane, store residual CO_(2) on site, and reduce carbon emissions. In this article, the characteristics of scCO_(2) were introduced, the relevant mechanism of scCO_(2) development of coal bed methane was briefly described, the key technologies of the scCO_(2)-ECBM process were discussed, the research status of scCO_(2) intensified recovery of coal-bed methane was analyzed, and it was pointed out the realization of large-scale, efficient, scientific and environmental protection integration of CO_(2) geological storage in coal reservoirs and coalbed methane recovery should be a goal of the next stage of coal bed methane development.
