| 摘 要： | 煤层既是煤层气的生气源岩 ,又是储集岩 ,但煤层围岩的性质、构造、水动力系统对煤层气藏的形成以及煤层气可采性的影响是不可忽视的。经对煤层围岩储气性、围岩构造发育程度及水动力条件与煤层气藏的形成进行分析 ,指出在对煤层认识的同时 ,也要对煤层围岩及围岩构造进行研究。提出在勘探过程中 ,将煤系地层在一定范围内视为一个煤层组合是适合我国低渗、低压的煤层特点和当前技术装备水平条件的切实可行的方法

| Abstract: | Coal bed is gas source rock as well as reservoir rock of coal bed gas, but effect of properties, structure, waterpower system of coal bed surrounding rock on the formation of coal bed gas reservoir and recoverable coal bed gasvolume is not negligible. Analysis of gas storage capacity of coal bed surrounding rock, development ofsurrounding rock structure,water power conditions and formation of coal bed gas reservoir indicates that,whileunderstanding coal bed,coal bed surrounding rock and surrounding rock structure should be also studied. Thispaper puts forward that,in the exploration process,considering a certain range of coal measure strata as a coal bedgroup is a realistic way suitable to coal bed features of low permeability,low pressure and present technical leveland equipment conditions in our country. |
