摘　　要：对焦作矿区二１煤储层特征及其主要影响因素进行了系统的分析，结果表明，本区煤层气具有含量高、煤储层压力略高于静水压力、气饱和度较高和煤吸附性能较强，但煤层的渗透性较差和储层温度较低等特征．由于煤变质及其演化、断块构造及其差异升降运动和三叠纪末抬升剥蚀以及第三、四纪局部快速沉降等因素，对煤储层特性产生了显著的影响，使本区煤储层特征分布具有明显的差异性．The properties of Ⅱ 1 coal seam reservoir and influencial factors are systematically analyzed. The research shows that the reservoir is characterized by high gas content and saturation, good absorbability, but low permeability and temperature. And the reservoir pressure is higher than the hydrostatic pressure. The factors influencing the properties of coal reservoir include coal metamorphism and evolution, faulting block structure pattern , uplifting erosion at the end of Triassic, and the local rapid subsidence in Tertiary and Quaternary Periods.
