煤成气 含煤岩系中腐殖型有机质在煤化作用过程中生成的烃类气体（主要为甲烷气），为天然气的重要组成部分。 煤成气气源主要有两类：①富集型有机岩──煤层；②分散型有机岩，以含腐殖型（Ⅲ型）有机质为主的岩层，如碳质泥岩、页岩、沙质泥岩等。有时还含少量混合型有机质（Ⅱ型）岩层，如湖相泥岩等。 有机质在不同地质演化阶段，从生物化学作用到热作用（见煤化作用），可不断生成烃类气（甲烷及同系物）和非烃气 (C O2、N2、......)。未成熟阶段生成生物气（甲烷干气）；成熟阶段生成与"煤成油"相伴生的湿气、凝析气；高熟-过熟阶段生成裂解干气。 煤成气主要赋存于含煤岩系的各类储层中，亦可运移到非煤系储层中。按其赋存状态又可分为以下两类：①煤层气。是一种储存在"煤层"的微孔隙和裂隙中的、基本上未运移出生气母岩的天然气，属典型的自生自储式的非常规天然气藏。由于煤层一般致密,透气性差,吸附性强,一般不易解析出气体,有时有部分呈游离状态集中在煤层中，采煤中形成瓦斯突出造成灾害。在适当的地质条件下亦可形成工业性气藏，又称煤层甲烷气。②煤生气。由生气母岩（煤层、碳质泥岩、泥岩）中扩散、运移出来的部分煤成气。聚集并储存于其他储层（如砂岩、砾岩、灰岩）中，可形成不同规模的常规工业性气藏，是煤成气的主要部分，为勘探、开发主要对象。有的逸散于空气中,溶解于地下水或分散于母岩围岩中,不具有工业价值。
