| 摘 要： | 煤层气是一种与煤岩同生共体以甲烷为主要成分,主要以吸附状态赋存在沉积盆地煤层之中的可燃气体,也就是煤矿生产中有名的瓦斯气。煤层气藏作为一种非常规常气藏,从地质成因与特征,储集与开采特征以及储量评价多个方面,与常规气藏有着不同之处,因此对两种类型的气藏进行详细的比较与总结十分必要,同时也为煤层甲烷气开发与开采中的各项研究如煤层气藏工程,煤层气井试井,完井,煤层气藏模拟等奠定了基础。

| Abstract: | Coalbed gas is combustible and primarily adsorbed on the internal surface of coal matrix,whose main component is methane which coexists with coal petroloy.As an unconventional gas reservoir,there are many differences between coalbed gas and conventional gas reservoirs.In this paper,comparison and summarization of these two gas reservoirs are made from the points of their geological reasons and characteristics,and their accumulation and exploitaion to gas-in-place calculation,which lay a sound foundation for coalbed gas reservoir engineering,well testing,completion and coalbed gas reservoir simulation etc. |

| Keywords: | coalbed gas reservoir characteristics comparison origin exploitation reserve evaluation |
