摘要
通过松河井田煤层气探井及相关资料,论证了该区峨眉山玄武岩组煤系夹层 32#煤层发育情况、煤层特征等;对比分析了玄武岩组煤系夹层 32#煤与龙潭组 3#煤在煤体结构、煤层厚度、渗透率、含气性等煤储层特征,认为玄武岩组 32#煤层气抽采前景较好,可作为龙潭组煤层气地面抽采的有效补充.
Abstract
Based on the CBM exploration well and relevant data in Songhe well field,the development and characteristics of No.32 coal seam in the Basalt formation of Emeishan in this area are demonstrated.The characteristics of coal reservoir,such as coal body structure,seam thickness,permeability and gas bearing,are compared between No.32 and No.3 coal in Basalt formation.It is concluded that No.32 CBM in Basalt formation has a good prospect and can be an effective supplement for surface CBM extraction in Longtan formation.
