摘要
等温吸附实验在煤层气含气量测试中应用较成熟,因此,当前的页岩室内含气量测试中也应用此法,然而,在页岩的等温吸附实验中,出现"倒吸附"现象,所测得的VL和PL出现负值。通过对样品的制作、处理、测试过程、测试结果和其他辅助实验成果分析,对产生"倒吸附"可能的情况进行了总结,并对实验和评价参数等方面提出相关建议。
Application of isothermal adsorption experiment in the coal-bed gas content test is mature,and it should also be used into the shale indoor gas content test.However,the phenomenon of＂inverted absorption＂occurred in the isothermal adsorption experiment with minus value of VL and PL.The possible situation for appearing＂inverted absorption＂are summarized and relevant suggestions are presented for experiment and evaluation parameters by analyzing the sample＇s making,treatment,testing process,testing results and other auxiliary test results.
