为了评价山西寿阳北区块煤层气资源的开发潜力,通过搜集区内以往煤层气勘探成果以及煤层气参数井资料,从地质条件、煤层发育情况、含气性、煤储层特征等方面进行分析,分析结果表明:本区具备煤层气富集成藏的条件;山西组3号、太原组9号、15号煤层是该区目的煤层,其中15号煤层为主力煤层;该区东北部构造简单,主力煤层较发育,埋深适中,煤层较厚、含气量较高、渗透率较低,封盖性良好,是下步煤层气勘探开发的有利区。

In order to eveluate the development potential of coalbed methane resources in the North Block of Shouyang,with the collection on the previous coalbed me thane exploration achievements and the coalbed methane parameter well information,Shanxi,an analysis was conducted on the geological condition,seam development,gas bearing,coal reservoir features and other aspects. The analysis held that the block would have the enrichment occurrence conditions of coalbed methane. No. 3 seam of Sh anxi Formation,No. 9 and No.15 seams of Taiyuan Formation would be target seams in the block and No.15 seam would be the main seam.The structure in the northeast p art of the block would be simple, the main seam was well developed with the moderate buried depth,the high seam thickness,the high gas bearing,the low permeability and t he good sealing and would be the favorable block for the next exploration and development of coalbed methane.
