摘要
山西柳林煤层气区块的煤系地层是在奥陶系海相碳酸盐岩基础之上发育的一套包含了灰岩、煤层和碎屑岩在内的海相、海陆交互及三角洲相的石炭-二叠系沉积地层层序。所有这些地层在以往的工作中已得到充分鉴别,并且在区块东部均有出露。通过对地质标志层的特征描述并结合测井资料所做的地层对比,进而深入了解了该区煤系地层的横向展布格局。
The coal bearing sequence of Liulin CBM block developed overlying the basal Ordovician marine carbonate.It is composed of Permian-Carboniferous coal seams with marine limestone,shale and transitional-deltaic clast sediments.All these sequences are well defined by extensive studies and can be observed in outcrop along the eastern portion of the block.To provide the description work of the geological markers that can be combined with well-logging correlation to understand and gain insights into the geometry and lateral continuity of the coal seams.
