摘要
煤储层的渗透性预测是煤层气开发前必须的储层评价工作。评价方法是依据围岩节理及煤层裂隙的宏观、微观统计分析，寻找区内裂隙发育带及其走向，预测高渗透区的分布。
The prediction of coal reservoir permeability is the necessary work for reservoir evaluation berore the development of coalbed methane.The adopted is based on the possibilities of finding the fracture developed zones and their strikes in the region and predicting the high permeable areas by the macro and micro statistical analyses of the joints in enclosing rocks and the fractures in coals.
