摘要: 通过对美国粉河盆地以及我国铁法盆地煤层气富集规律的解剖,总结出影响低阶煤煤层气富集的关键因素是封堵,而构造、岩性和水动力是形成煤层气封堵的主要因素。同时提出了5种不同的煤层气富集模式,即背斜模式、构造—水动力模式、构造—岩性模式、岩性—水动力模式和岩性模式。

Abstract: By analysis of enrichment law of coalbed methane in Powder River Basin in USA and Tiefa Basin in China, it summarizes that the plug-backing is the key factor to affect the enrichment of lower-rank coalbed methane, the main factors to form plug-backing of coalbed methane include tectonics, rocks and water momentum. Meanwhile, it is put forward that 5 various modes of coalbed methane enrichment, including anticline mode, structure-water momentum, structure-lithologic mode, lithologic-water momentum mode and lithologic mode

Key words: lower-rank coal, coalbed methane, enrichment mode
