摘　　要：通过分析尼勒克煤田胡吉尔台南部矿区煤储层物性和含气性特征,系统提高对矿区低阶煤层气的认识。从各项参数得出,尼勒克煤田胡吉尔台南部矿区煤层气地质条件优越,具有进一步勘查开发的潜力。此外,通过类比分析煤层气赋存特征,优选出伊宁煤田作为新的煤层气勘查开发区块,初步估算预测煤层气资源量超6000亿m3。其次,总结尼勒克县胡吉尔台南部区块煤层气埋藏深度较大的特征,可扩大煤层气勘查范围至新疆其他浅部(0~800m)无气藏显示或显示差的区块,对新疆下一步煤层气选区评价工作具有指导意义。By analyzing the physical property and gas-bearing characteristics of coal reservoirs in the southern Hujiltai Mining Area of Nileke Coalfield, the understanding of low-rank coalbed methane in the mining area is systematically improved. It can be concluded from various parameters that the coalbed methane geological conditions in the southern Hujiltai Mining Area are superior, indicating the potential for further exploration and development. In addition, through an analogous analysis of coalbed methane occurrence characteristics, the Yining coalfield is selected as a new block for coalbed methane exploration and development. Preliminary estimates predict a coalbed methane resource volume exceeding 600 billion cubic meters. Furthermore, the study summarizes the characteristics of greater burial depth of coalbed methane in the south Hujiltai block of Nilecke County, and proposes that the coalbed methane exploration scope can be expanded to other shallow(0~800m) blocks with no or poor gas reservoir display, which has, provides valuable guidance for the next phase of coalbed methane prospecting and assessment in Xinjiang.
