我国煤层气成分变化及时空分布特征

Distribution and time-space characteristics of coalbed gas composition in China

摘要: 通过对我国主要煤矿区煤层气含量的测试,连续追踪采集气体样品进行成分分析,探讨了气体成分随时间推移及空间方位变化的地球化学效应,了解煤层气体成分横向及垂向的变化特征。

Abstract: The gas content measurements in main coal mining areas are performed,while the gas samples are tested for gas compositions.Based on test results the geochemistry of gas compositions with the time-space changes is discussed,understanding the distribution characteristics of coalbed gas composition in horizontal and vertical directions.
