针对焦作煤田埋深1000 m以深的含气量数据很少,不能满足深部煤层气资源量评价的要求,需要在全面了解本区煤层气的富集和分布规律的基础上,对深部煤层含气量进行预测。本文主要讨论采用含气量梯度法和温度-压力-吸附曲线法来进行预测深部煤层含气量。
In view of the fact that the data of gas content at a depth of 1000 m deep in Jiaozuo coalfield are few and can not meet the requirements of deep CBM resources evaluation, it is necessary to fully understand the CBM enrichment and distribution in this area, prediction. This paper mainly discusses the prediction of gas content in deep coal seams by gas-content gradient method and temperature-pressure-adsorption curve method.
