新疆后峡盆地煤层气井单井产量差异悬殊，单井产量控制因素不明确，采用统计分析、线性回归分析法和灰色关联数学分析法，对煤层气井单井产能影响因素进行了定量表征。基于后峡盆地煤层气井单井产能差异性，煤层气井主要被划分为了3种不同的类型；I类煤层气井储层特征好，采用较小的加砂强度和加液强度，结合较小的压降，排采效果好；III类煤层气井储层特征较差，尤其是含气量较低，采用同样的储层改造手段和排采制度较难获取好的排采效果。对筛选的22个影响煤层气井产能的因素进行定量评价分析，研究表明：含气量对煤层气井产能具有显著的控制作用，而储层改造程度和排采制度的合理制定，是煤层气井高效生产的关键。

The coalbed methane production of single-well varies widely and low in Houxia Basin, Xinjiang, indicating complexity control factors on the coalbed methane productivity. The statistical analysis, linear regression method and grey correlation mathematical analysis method were utilized to quantitatively characterize the screened factors affecting the single-well production capacity of coalbed methane wells. Based on the single-well capacity of coalbed methane wells in Houxia Basin, coalbed methane wells can be mainly classified into three types. Class I coalbed methane wells have good reservoir characteristics, and the drainage and production effect is good by using small sand and liquid addition strength combined with small pressure drop; class III coalbed methane wells have poor reservoir characteristics, especially low gas content, and it is difficult to obtain better drainage and production results by adopting the same reservoir reconstruction means and drainage and production system. Based on the quantitative evaluation and analysis of 22 factors that affect the productivity of coalbed methane wells, the research shows that the gas content has a significant control effect on the productivity of coalbed methane wells, and the reasonable formulation of reservoir reconstruction degree and drainage and production system is the key to the efficient production of coalbed methane wells.
