焦作煤田煤层气资源特征及开发利用研究

煤层气是国家高度重视和亟待勘查开发的重要能源矿种,也是我国紧缺与需要的战略能源.通过对焦作煤田煤层气地质条件、资源特征及开发利用方法现状的研究,认为焦作煤田具备煤层气开采条件及煤层气赋存地质条件;焦作煤田有大面积的石炭二叠系含煤地层分布,并且含煤层数多,煤层较为稳定,储量大;因此,焦作煤田拥有丰富的煤层气资源,含气饱和度和煤层渗透率较高,资源密度高,有利于煤层气开发利用.焦作煤田煤层气的开发对改善焦作市能源供给结构,提高资源利用率、保护生态环境具有重要意义.

Study on the Charactersitics and Exploitation of Coalbed Methane in Jiaozuo

Coal bed gas is an important energy ore,which should be have a close attention and needs to be reconnoitried and developed quickly,also it is the scarce and strategic energy of our country.By the study of geological condition,resource characteristic and method of development and utilization,the author thinks that the coal field in Jiaozuo possesses the geological conditions to exploit and compose coal bed gas.The sthone charcoal stratum and permian system which contain coal,is in large area of Jiaozuo coal field,and coal seams comparatively stable and large in reseves.Therefore,there are abundant coal bed gas resources in the mining area of Jiaozuo which is relatively higher in the saturation degree and penetrance of coal seam,highly density of resoures,and is helpful for coal bed gas utilization.The development of the coal bed gas of the mining area in Jiaozuo has the significance of improving the structure of energy supply,resources utilization ration and ecological environment protection in Jiaozuo.
