| 摘 要： | 煤和煤层气地质勘探需要在取到钻孔煤心后的很短时间内获得气含量测值,而现行的煤层气含量测定方法难以满足此要求。基于自然解吸法原理和方法,以自然解吸法的测定结果为基准,在保证解吸量、气组成及其含量基本不变的前提下,通过连续观测、适当提高解吸温度等途径,合理、有效地加速解吸。以快速测定法与自然解吸法的对比试验结果为依据,建立了煤层气含量快速测定方法。此方法将煤层气含量测定周期缩短为几h~几d,可以满足煤和煤层气勘探的需求。

| Abstract: | It is usually required that the gas content determined on coal cores is delivered rapidly in the course of coal and coalbed methane(CBM) exploration.However,the existing method of CBM content determination is hard to meet the requirement.Based on the principle and methodology of CBM natural desorption,on the basis of the result of natural desorption,and under remaining the desorbed volume,gas composition and its content basically unchanged,the gas desorption rate is sped up reasonably and effectively by the... |
