中文摘要：
Panguan 向斜包含丰富的煤资源，它可以是 coalbed 甲烷的潜在的来源。以便在这个区域评估 coalbed 甲烷生产潜力，我们调查了 coalbed 甲烷水库的毛孔破裂系统，并且由使用各种各样的分析方法分析了煤气的吸着和渗出物能力包括扫描电子显微镜学( SEM )，光显微镜学，水银注射测试，低温度的 N2 等温线吸附/解吸附作用分析，低地的原子磁性的回声和甲烷等温的吸附大小。结果证明在 Panguan 向斜的煤水库的样品有中等煤气的吸着能力。然而，在学习区域的煤有有利渗出物能力，并且为 coalbed 甲烷生产是传导性的。在 Panguan 向斜的 coalbed 甲烷水库的物理性质被煤变态通常控制：低等级煤通常有低甲烷吸着能力和它的毛孔和 microfractures 糟糕被开发；当中等等级煤有更好的甲烷吸着能力，和它的渗出物时，毛孔和 microfractures 是开发的井，它为聚在一起的 coalbed 甲烷和探索是足够的。因此，在 Panguan 向斜的中等等级煤是为 coalbed 甲烷探索和生产的最未来的目标。
英文摘要：
The Panguan Syncline contains abundant coal resources, which may be a potential source of coalbed methane. In order to evaluate the coalbed methane production potential in this area, we investi- gated the pore-fracture system of coalbed methane reservoirs, and analyzed the gas sorption and seepage capacities by using various analytical methods, including scanning electron microscopy （SEM）, optical microscopy, mercury-injection test, low-temperature N2 isotherm adsorption/desorption analyses, low- field nuclear magnetic resonance and methane isothermal adsorption measurements. The results show that the samples of the coal reservoirs in the Panguan Syncline have moderate gas sorption capacity. However, the coals in the study area have favorable seepage capacities, and are conductive for the coalbed methane production. The physical properties of the coalbed methane reservoirs in the Panguan Syncline are gener- ally controlled by coal metamorphism： the low rank coal usually has low methane sorption capacity and its pore and microfractures are poorly developed; while the medium rank coal has better methane sorption capacity, and its seepage pores and microfractures are well developed, which are sufficient for the coalbed methane＇s gathering and exploration. Therefore, the medium rank coals in the Panguan Syncline are the most prospective targets for the coalbed methane exploration and production.
