摘要(Abstract)：
陕西省煤层气资源相当丰富 ,埋深 2 0 0 0 m以浅的煤层气资源量为 2 5 62 4 .88亿 m3。通过对五大煤田煤储层展布、煤层气含量、煤层渗透率、煤变质特征、煤的吸附性能等条件的综合分析以及煤层气资源量的计算 ,认为陕西省煤层气开发储层条件比较优越 ,煤层气勘探开发条件最好的地区为渭北和陕北石炭二叠纪煤田 ,韩城矿区可作为煤层气勘探开发的靶区
The CBM resource in Shaanxi Province is evaluated as 2 5 6 2 4× 10 8m3at shallower than 2 0 0 0 m .The com prehensive study,covering five coal fields,includes coal reservoir distribution,gas content,coal seam permeability,coal ranks and adsorption properties,in conjunction with resource calculation.It is considered that the potential of CBM developm ent in Shaanxi is very large,especially in Permio- Carbon coal fields in Weibei area and Northern Shaanxi.The Hancheng mining area is an optimum target area for development.
