摘要
采用汞注入法测试了内蒙古二道岭矿区主力煤储层的孔容、孔比表面积及孔隙率,分析了二道岭矿区主煤层的孔隙结构特征。结果表明,二道岭矿区主煤层总孔容较高,孔隙率较高,煤储层吸附能力较大,煤层气的运移潜势较大,有利于煤层气的开发。
By the use of mercury injection me th od,the authors tested main coal reservoir's pore volume,specific surface area and void factor in Erdaoling Mining Area,Inner Mongolia,and an analysis of por osity features was made.The result reveals the main coal reservoir's high total pore volume,high void factor and high adsorptive power,so a high coalbed meth ane migration potential as well.It is advantageous to coalbed methane exploitat ion.
