摘要
通过对辽河坳陷东部凸起煤层的厚度、埋深、煤层分布、煤岩煤质、煤岩组成等基本地质特征分析以及对煤层含气量、煤层资源量的研究,认为辽河坳陷东部凸起具有含煤面积大,分布稳定,埋藏适中,煤层含碳高,亮煤成分多,灰分含量低,含气量高,煤层气资源量大,气源供给充足的特点,具备煤层气勘探潜力。
For coalbed methane,an unconventional gas,the gas source condition is the basis to form coalbed gas reservoirs.In this study,some fundamental features of coal seam in the Eastern Uplift,Liaohe Depression,are presented,including the thickness,burial depth,distribution,the property and composition of coal rock,and the gas content and resources of coal seam.Results show that the coal seam is characterized by large coal-bearing area,stable distribution,moderate burial depth,high carbon content,large quantity of bright coal,low ash content,high gas content,abundant coal resources,and sufficient gas supply,resulting in an exploration potential.
