| 摘 要： | 为了揭示煤层气地面开采的影响因素,通过分析刘家煤层气区块煤层气资源条件、煤层气地质条件、煤层气钻井工艺及排采工艺,研究了刘家区块开采取得成功的原因。阜新刘家煤层气藏埋藏适中、煤层多且厚;盖层和断层的封闭作用、岩浆岩的圈闭封阻作用以及变质作用使刘家区块形成了局部富集的小区块。刘家区块依据区内火成岩和断层布局建井,以及根据地质条件合理的进行煤层气钻井和排采工作,是刘家区地面开采取得成功的重要因素。刘家区块煤层气地面开采的成功为其他煤层气区块的地面开采提供了依据和参考。 |

| Abstract: | In order to reveal the influence factors of coalbed methane ground mining,through the analysis of Liujia CBM block's CBM resources conditions,CBM geological conditions,CBM drilling technology and venting and mining production technology,the reasons for the success of block mining was studied.The CBM of Liujia in Fuxin buried moderately,coal seams are much more and thick;the sealed function of cover layers and faults,the closed and separate function of magmatic rocks and metamorphic function make Liujia bloc... |
