| 摘 要： | 煤层气是储集在煤层中的非常规天然气.煤层中发育有微孔隙系统和裂隙系统，煤层气主要以物理吸附的形式赋存于煤的内表面上，当压力降低时，煤层气发生解吸、扩散和渗流，最后由井筒中产出.了解煤层气的赋存、运移机理及产出特征，对进行煤层气的可采性评价十分重要.

| Abstract: | Coal Bed Methane is an unconventional natura gas which is stored in coal bed. The micro-openings system and the fracture system develop in coal bed, the gas is absorbed in the inter-surfase of coal, when the pressure is decreased, the gas begin to desorb, diffuse, flow and ultimately produce to surface from well hole. Understanding the storage and transport mechanism and production charateristics of coal bed methane is very important to it's developing ability assessment. |
