渗透率在煤层气开发过程中的变化规律及其对产量的影响

摘要

煤层气是一种清洁能源，具有较高的利用价值，尤其是在能源越来越短缺的背景下，环境压力和煤矿生产的形势越来越严峻，对其进行合理开发意义重大。主要对煤层气开发过程中渗透率的变化规律及其对产能的影响进行的详细阐述。%Coalbed methane(CBM)is a kind of clean energy with high utilization value.Especially in the background of the shortage of energy,environmental pressure and coal mine production are becoming more and more serious,and reasonable exploitation is of great significance.The author mainly expatiates on the variation law of permeability and its effect on productivity in the process of CBM development.
