Experimental study on methane adsorption of coal bed from Sihe Mine in Qinshui Basin

  • 摘要: 煤储层具有大量的裂隙和孔隙,使煤岩具有很大的比表面积,为煤中甲烷的吸附提供了必要条件。采用自主研发的煤层气吸附装置,通过对沁水盆地寺河煤矿不同粒径煤粉的吸附性模拟实验,总结了不同粒径煤粉在吸附甲烷12 h内的吸附规律,计算出其中吸附气量,研究了吸附速率、吸附量的变化规律。研究认为:吸附的前10 min,吸附量占总吸附量的40%~60%,煤粉粒径越小,所占的比例越大,吸附越快;不同粒径煤粉的吸附量为15.1~29.1 mL/g,煤粉粒径越小,单位质量煤粉吸附量越大。通过对煤岩吸附规律的深入研究,为沁水盆地煤层气的勘探开发提供技术支持。
