【摘要】 从煤层气的解吸速度和可解吸量等方面,探讨了潘庄井田煤层气的解吸特征,分析了潘庄井田解吸速度与解吸时间、可解吸量与埋深的关系。指出区域上潘庄1号井田的中部地区,潘庄2号井田15煤大部分地区和3煤北部地带,煤层气的可解吸率很高,有利于煤层气的开发,但可解吸率在区域上随埋深的增加大多呈负相关关系,数据较为离散。更多还原

【Abstract】 Based on the analysis of desorption velocity and the capable desorption quantity of coalbed methane,we systemically discussed the desorption characteristics of coalbed methane of Panzhuang Coal mine and analyze the relationship between desorption velocity and desorption time,and the relationship between the capable desorption quantity and the burial depth of coal reservoir.In the area,there is quite high capable desorption rate in the middle area of the first mine field,most area of the fifth coal of the second mine field and the north area of the third coal of Panzhuang Coal mine,which is propitious to the exploitation of coalbed methane.In the layer region,the capable desorption rate mostly takes on a negative relationship with the increase of burial depth of coal reservoir,but the data is comparatively discrete.更多还原
