THE FEATURE AND MEASUREMENTMETHODS OF POROSITY ANDRELATIVE PERMEABILITY OF COAL RESERVOIR

摘要: 煤储层不同于常规的天然气储层,煤岩本身既是气源岩又是储集岩。作为储层,煤岩孔隙结构有其特殊性,煤层气的储集、产出机理也不同于常规储层。与常规油气储层对比,本文对煤储层的孔隙度,相对渗透率特征及其测定方法进行了介绍。Abstract: Coal gas reservoir is different from conventional gas reservoir.Coal is not only sourcerock but reservoir as well. As reservoir. there is special feature in pore texture in coal.And mechanism of accumulation and occurrence of gas in coal is also different from thoseof conventional gas reservoir on basis of comparison of coal gas reservoir with conventionalgas reservoir. the paper discussed the feature and measurement methods of porosity andrelative permeability of coal reservoir.
