CO₂-ECBM技术在河东煤田的潜力评估

摘要: 根据河东煤田地质构造、煤储层特性、含气性等煤层气地质条件的综合研究，对利用CO₂提高煤层气采收率技术（简称CO₂-ECBM技术）在河东煤田深部煤层（埋深1 000~1 500 m）开采煤层气以及埋藏CO₂的潜力进行了初步评估。结果表明，利用CO₂-ECBM技术增产煤层气资源量为0.26×10¹² m³，占煤层气总资源量的32.1%；CO₂埋藏量为12.18×10⁸ t，相当于山西省2013年CO₂排放量的3.2倍。

Abstract: On the basis of the integrated study of the geological conditions such as geological structures, properties of coal reservoir and gas-bearing properties in Hedong coalfield, the preliminary assessment of the potential for CBM extraction and concealing CO₂ was carried out by using CO₂-ECBM technique(for coal seams at depth from 1 000 m to 1500 m)in Hedong coalfield. The results show that CO₂-ECBM technique will increase 0.26×10¹² m³ of CBM resources, accounting for 32.1% of the total CBM resources, and the quantity of CO₂ storage will be up to 12.18×10⁸ t, equivalent to 3.2 times of CO₂ emission in 2013 in Shanxi Province.
