为了合理开采煤层气，需要对煤层气的不同阶段进行合理划分，并针对不同排采阶段相应制定不同的排采生产制度。综合对比评价了不同排采阶段划分方法的划分依据、阶段特征、划分方法的优缺点，提出了与生产控制相结合的煤层气排采生产六段划分法，将煤层气生产阶段划分为未见气阶段、初见气阶段、产气量上升阶段、产气量稳定阶段、产气量下降阶段和废弃阶段，给出了六段划分法在不同排采阶段生产控制方与法与技术对策，指明了六段排采阶段定量化研究的重要性。
為瞭閤理開採煤層氣，需要對煤層氣的不同階段進行閤理劃分，併針對不同排採階段相應製定不同的排採生產製度。綜閤對比評價瞭不同排採階段劃分方法的劃分依據、階段特徵、劃分方法的優缺點，提齣瞭與生產控製相結閤的煤層氣排採生產六段劃分法，將煤層氣生產階段劃分為未見氣階段、初見氣階段、產氣量上升階段、產氣量穩定階段、產氣量下降階段和廢棄階段，給齣瞭六段劃分法在不同排採階段生產控製方與法與技術對策，指明瞭六段排採階段定量化研究的重要性。

In order to mine coalbed methane reasonably,a division of different production stages of coalbed methane was needed,different drainage and production system also should be developed. In this paper,the authors comprehensively compared and evaluated the classifi-cation criterion,each stages characteristics,the merits and demerits of different division methods which were focused on different production stages. A six-stage division method of coalbed methane drainage and production system which was combined with production control were put forward. The method divided the drainage and production process into six stages,which were no gas period,initial gas period,gas pro-duction rising period,gas production stable period,gas production decline period and abandoned period. The production control methods and technical measures of six-stage division method were investigated. The importance of quantitative study about six-stage division meth-od was also researched.
