摘要
通过大量煤层气勘探井试验测试 ,对我国各时代不同煤级煤在储层温度和常压条件下气体解吸试验结果进行了系统研究 ,分析了解吸过程中气体析出的变化规律及煤层气解吸参数的变化态势 ,探讨了我国煤层气解吸特征的变化 。
A large sum of gas desorption results from different coal rank and different age coals in China, measured under reservoir temperature and atmospheric pressure, are systematically researched. And gas desorption regularities and variation patter of gas desorption parameters during gas desorption processes are analyzed, as well as the gas desorption characteristics of coal seams in China are discussed, providing basic theoretical foundation for improving coalbed gas production rate.
