煤化程度
degree of coalification的用法详解
在石油工程中,degree of coalification(煤化度)是矿物岩石中煤层煤成熟程度的定义。煤化度用来衡量岩石中煤层交代程度,以确定煤层可利用性。煤化度可以通过野外观察,煤样试验或样品分析来测定。
煤化度可以用来衡量煤层对开采难度的影响,例如,煤层中水分含量越高,煤灰制程越多,开采难度越大。另外,煤化度可用来预测煤层开采时释放的热能,以及煤层中可利用煤种数量。
此外,煤化度还可用于判断煤层中煤质稳定性和热值。高煤化度的煤种热值较低,煤质稳定性较低,而低煤化度的煤种具有较高的热值,煤质稳定性较高。因此,煤化度的大小可以用来确定开采难度,以及煤层中可利用煤种数量和煤种质量。
