摘要
滇东晚二叠世含煤岩系良好的岩性组合，贮藏了丰富的煤层气资源。据勘探钻孔和矿井生产提供的气源量分析测试成果显示，煤层气中甲烷含量极为丰富。笔者对该区影响煤层气赋存的控制因素作了深入探讨，从成煤的构造环境、成侵演变和煤层气的保存条件等方面，提出了主要控制因素是埋深和构造，并且对煤层气的富存规律作了较为详尽的阐述。
The excellent rock assemblage of Late Permian coal -bearing rock series in East Yunnan contains abundant seam gas resources. According to the analysis and test of the gas from exploration drilling hole and well production, the methane content in the seam gas is very plentiful.This paper profoundly discusses the factors controlling the seam gas formation in this region- Basing upon the structural environment of coal formation, the evolution forming hydrocarbon and the reserve condition of seam gas, we consider the buried depth and the structure to be the main controlling factors and interpret in detail the concentrate and reserve law of seam gas.
