摘　　要：基于沙尔湖地区测井及钻孔资料,为进一步探究研究区煤层气成藏机理,运用实验、数值分析的方法,在考虑沉积环境和构造因素的情况下,对研究区样品进行了煤岩、煤质、镜质体反射率、孔裂隙等方面的研究。结合该地区煤层厚度、储层压力及顶板岩性,将影响煤层气成藏的因素归集到从煤层气生成到产出的各个阶段。通过对各个阶段内多种影响因素的综合分析,对沙尔湖地区煤层气成藏特征取得新的认识。以此为基础,通过对比现有开发技术,对未来沙尔湖地区煤层气开采提出合理化建议。Based on the data of geological surveying and drilling of Shaerhu area,in order to find the reservoir forming characteristic of coalbed methane（CBM）,taking in the consideration of sedimentary environment and structural factor,by using the methods of experimental comparision and numerical analysis,some test on the samples about coal rock,coal quality, vitrinite reflectance,pore and fracture have been reserched,at the same time,the author also collects some data about coal seam thickness,reservoir pressure and roof lithology.After that,they were distributed to four blocks,such as hydrocarbon generation stage,reservoir stage,sealing conditions,migraion conditions.Through the study on these factors in every stage,the results come out,after the integration of these four stage of reservoir forming characteristic,the author get some father understanding about the reservoir forming characteristic of coal bed methame（CBM） in Shaerhu.Base on this study,the author put forward some suggestion through the comparision of existing mining technology.
