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1000~1500 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。
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 CO2was 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 0.26×1012m3 of CBM resources, accounting for 32.1% of the total CBM resources, and the quantity of CO2 storage will be up to 12.18×108t, equivalent to 3.2 times of CO2 emission in 2013 in Shanxi Province.
