| 摘 要： | 煤层气独特的解吸/吸附机理决定了其储量评价方法与计算技术有别于常规天然气。力图把煤层气、煤炭、天然气储量规范中的相关内容有机地结合起来,进一步阐述《煤层气资源/储量规范》中评价与计算探明储量的基本要求,探讨了如何确定计算条件、单元划分和计算方法,如何选取储量计算参数等方面的技术问题。在对煤层气采收率预测方法评述的基础上,借助于已提交储量报告的研究成果,提出综合求取采收率,按气藏分别赋值的观点,以达到使储量计算结果更加合理和科学的目的。

| Abstract: | The unique desorption/adsorption mechanism of coalbed methane (CBM) determines that its evaluation is different from the conventional natural gas. This paper attempts to combine the criteria of CBM, coal, and natural gas reserves organically, elaborating the fundamental requirement on evaluation of proved reserves in CBM Resources and Reserves, discussing how to determine evaluating conditions, unit division, and evaluating methods, and how to select reserves evaluating parameters. Based on the predicting m... |
