摘要
对我国煤储层的等温吸附资料进行了全面系统分析和总结 ,得出了干燥煤样等温吸附曲线校正为储层温度和平衡水条件的回归经验公式。在此基础上 ,探讨了我国各时代、各煤类等温吸附常数 a、b值的地域和层域分布规律及其对煤层气地面开发的影响。
Based on a systematic analysis on coal reservoir adsorption data,the empirical regression formula is established,which corrects adsorption isothermal curves of coal samples(moisture free basis)for conditions of equilibrium moisture content and reservoir temperature.Accordingly the regional and vertical distribution regularities of isothermal adsorption contents(a,b values)of coal reservoirs in different geological time and dfferent coal ranks in China,as well as their effect on coalbed gas surface development.
