煤田地质钻孔瓦斯资料主要分布在1000m以浅,因而深部煤储层含气量的准确预测成为煤层气资源评价中亟待解决的问题。本文依据矿区15号煤浅部已有的含气量资料、煤的等温吸附曲线、储层压力梯度等数据对矿区深部的煤储层含气量进行了预测。
Coal mine geological drilling gas data are mainly distributed in shallow 1000m, so accurate prediction of gas content in deep coal reservoirs has become a problem to be solved in the CBM resource evaluation. In this paper, based on the existing gas content data in No.15 coal mine, the isothermal adsorption curve of coal and the pressure gradient of reservoir, the gas content of coal reservoirs in the deep mining area is predicted.
