摘要
阜康矿区煤层气地质条件中等,且随埋深明显形成分区,文章从地层、构造、煤层、煤质、烧变岩、水文地质条件进行分析,总结阜康矿区煤层气赋集规律,提出如下观点;阜康矿区煤储层条件与沁水、保德等国家煤层气基地储层条件有明显的差异,最大不同在于地层产状,沁水、保德盆地煤系产状平缓,而阜康矿区煤储层属于大倾角煤层,煤层大倾角使煤层气在深度上形成明显分区;阜康矿区普遍古火区发育,使煤层气风化带埋深加大;阜康矿区煤层气开发有利区为:古火区发育区适合开发深度600~1000m,煤层渗透率大于1mD。
The geological condition of coalbed methane in Fukang Mining Area is medium,and divisions are formed with the depth.The paper analyzes the strata,structure,coal seam,coal quality,burnt rocks and hydrogeological condition,and summarizes the occurrence rules of coalbed methane in the area.It’s proposed that there are remarkable differences in coal reservoir conditions between Fukang Mining Area and such National Coalbed Methane Bases as Qinshui Basin and Baode Basin,especially the stratigraphic occurrence.The stratigraphic occurrence in Qinshui Basin and Baode Basin is gentle,while the coal reservoirs in Fukang Mining Area belong to coal seams with large dip angles,which causes the obvious division of coalbed methane occurrences in depths.Ancient fire area generally develops in the area,and the burial depth of the coalbed methane weathering zone increases.The favorable area for coalbed methane development in Fukang Mining Area is the developed ancient fire area with a burial depth of 600~1000 m and a coal seam permeability of more than 1mD.
