摘要
以焦作矿区地质勘探钻孔的瓦斯测试、井下抽放试验资料为基础,对焦作煤田山西组煤层气资源、储层特征等进行了论述和评价,并对本区煤层气开发的有利地段和开发方法进行了探讨。本区虽然煤层气资源赋存条件较好,资源丰度高,但因其处于欠饱和、低压—超低压状态以及渗透率较小的情况,为了取得煤层气开发的新突破,建议采用井下抽放与地面排采相结合的方法。
Based on the gas testing of geological prospecting hole and exhaust testing informations of well in Jiaozuo mining area,review and evaluation on coalbed gas resources and features of reservoir of Shanxi formation in Jiaozuo coalfield,and probed into the favourable exploitation section and exploitation method of coalbed gas in the area.In the area,although there are better preser-vative condition of coalbed gas resources and higher abundance of resources,but because of it under the cases of not enough satu-ration,low pressure～over low pressure and lower permeability,so in order to obtain new breakthrough of coalbed gas exploitation,suggest that ought to use the method combine exhaust in well and mining on the ground.
