基于层次分析法(AHP)的煤层气区块产能潜力分区——以山西柿庄镇北区块3~#煤为例

CBM Block Capacity Potential Partitioning Based on AHP——A Case Study of Coal No.3 in Shizhuang North Block,Shanxi

划分煤层气产能潜力区,弄清地下资源展布特征,对节约勘探成本,早日实现经济效益具有重要意义。以柿庄北区块3#煤为例,选取对煤层气产气情况有重要影响的地质因素,将这些地质因素分为开采条件和资源条件两大类;然后通过层次分析法,为各地质因素赋权重并分级赋值;最后根据所求结果对柿庄北区块进行产能潜力区划分,并运用实际生产资料对划分结果进行验证。希望我们的工作可以对本区以后的煤层气勘探开发提供指导,为其他区块相关研究提供借鉴。

To partition CBM capacity potential blocks,make clear underground resource extending features have great significance in exploration cost economization and economic benefit realization earlier. Taking the coal No. 3 in the Shizhuang north block as example,to choose geological factors impacting CBM production situation significantly,have partitioned the factors into exploitation requirement and resource requirement two categories. Then through the AHP,weighting the factors and hierarchically assigned. Finally according to required result carried out capacity potential partitioning in Shizhuang north block,then applying practical production data carried out validation. Hope our study can provide guidance for CBM exploration and exploitation in the area henceforth.
