| 摘 要： | 通过对焦坪矿区下石节煤矿JPC-01井煤储层基本参数进行分析,认为本区为地温正常区欠压储层,煤层吸附能力为低～中等,含气饱和度偏低,煤层处于欠饱和状态,含气量较小;由于煤体结构主体为原生结构煤,渗透性相对较好。虽然煤的变质程度较低（不粘煤）,但矿区构造简单,主要煤层厚度大,排水采气地面抽采试验显示,该井创造了我国在侏罗纪低煤级低含气量煤层中日产气超过1 000m3的记录,煤层气资源潜力较大。建议进一步开展煤层气地面抽采试验工作,为矿区瓦斯治理,探索地面瓦斯预抽采开辟新的途径。

| Abstract: | Based on basic parameters analysis of coal reservoir in the JPC-01 well,Xiashijie coalmine,Jiaoping mine area,considered that the area has an normal geotemperature,underpressure coal reservoir,low to medium coal seam adsorptive capacity,gas saturation on the low side,coal seams are in undersaturated condition,gas content on the small side.The main coal mass structure is primary with relatively good permeability.Although degree of coal metamorphism is lower(non-caking coal),but mine area structure is quite s... |
