煤层含气量模拟试验方法及应用

Coalbed gas content simulation test and application

利用IS - 10 0等温吸附仪的高压吸附罐、精确的控温系统 ,配备气体电子流量计 ,并编制了控制程序 ,建立了煤层气含气量模拟试验方法。模拟试验方法的建立 ,可以全程模拟煤层气从提钻取心到解吸结束 ,了解含气量测试过程中煤层气的解吸规律 ,求取任意时间对应的逸散气量 ,为多种方法求取逸散气量的对比研究提供了方便。

With high pressure canister and accurate thermoregulation system of IS 100 isotherm instrument and an electronic flow meter,a type of gas content simulation method is established.Meanwhile,a control program is combined to control data acquisition.Base on simulated results,the whole gas desorption process from coring to end can be understand and find out gas desorption regularities,get lost gas content at any time that is sited in test.The study would be available for comparing multiple approaches to calculate lost gas.
