摘要：

在CO₂的捕获和埋存技术中，深煤层CO2埋存技术堪称非零和博弈的典范。CO₂在深煤层的埋存不仅可以减少温室气体，同时可以驱替煤层中的CH₄气体，达到煤层气增产目的。然而，由于目前对深部煤层储层特性的研究还较为局限，深煤层CO₂埋存技术还存在诸多问题亟待解决。阐述了深煤层CO₂埋存技术的发展现状，归纳总结了目前主要存在的4大技术难题，即流固耦合问题、CO₂超临界吸附问题、埋存安全问题和地质工程整合问题，并初步探讨了解决以上问题的研究方向，强调进一步补充实验数据和数值模拟是目前技术攻关的当务之急，提出“建立深煤层CO₂可封存性评价体系”的概念。

Abstract:

Carbon Dioxide Sequestration Technology in deep coal seam is regarded as a typical case in reducing emission and impelling methane out from coal seams, increasing the coal bed methane production. However, the research on the deep coal seam reservoir has little advances, leaving many technical issues to be resolved. This paper expands the status of carbon dioxide sequestration in deep coal seam, summarizes the four technical issues, including fluidsolid coupling issue, carbon dioxide ultracritical absorption issue, sequestration safety issue and geological engineering issue, and presents hints to these issues. It is suggested that further testing data and stimulation is the technical solution. A concept of establishing an evaluation system in carbon dioxide sequestration technology is also presented.

Key words: carbon dioxide sequestration, deep coal seam, technical issues, solution
