摘　　要：在岩石含气量测试方法现状调研基础上,详细介绍了自主研制的基于自动化排水集气原理的页岩含气量测试装置,阐述了仪器原理、功能,并采用6种不同气体在快、慢两个不同流速下,研究气体组成及流速对质量流量计法和自动化排水集气法测试精度的影响。结果表明,质量流量计法受气体组分及流速影响显著,尤其当烃类气体组分不确定或含水蒸气时,会出现较大误差,高流速条件下误差可达10%以上。自动化排水集气法计量精度高,误差在1%以内,且对流速变化不敏感,实现了高自动化与高精度。This paper introduced a self-made instrument based on automated water repelling and gas collecting principle,and compared with mass flow meter method.The results showed that gas component and flowing rate had great influence on mass flow meter method.When testing gas had uncertain ratio of other hydrocarbon gases and water steam,the error was larger than 10% under fast flowing rate.On the contrary,the error of automated water repelling and gas collecting method was less than 1%,and flowing rate had nearly no impact on results.
