吐哈盆地煤层的吸附性及其影响因素

Adsorptive charateristics and controlling factors of coal seams in TU-Ha basin

摘要: 通过对吐哈盆地煤层的吸附性及其影响因素的深入研究,认为该盆地煤层虽然变质程度较低,但对甲烷气仍有较强的吸附能力;煤的变质程度是影响吐哈盆地煤层吸附性的主要因素,煤岩显微组分、煤中水分和含油性也对煤层吸附性有不同程度的影响。

Abstract: The research on adsorptive characteristics and controlling factors of coal seams in Tu-Ha basin indicated that the methane adsorptive capacity is still strong,although the rank of coal seams are relatively low,which is the major controlling factor for adsorptive capacity of coal seams.The other factors,such as maceral components,moisture content and oil-bearing property,have also different degree of influence.
