页岩中气体组成实验测定方法分析

Analysis of experimental determination method of gas composition in shale

通过碎裂释气方法与质谱、色谱分析相结合,通过分析结果对比提出了适合页岩中气体组成的测定方法。研究结论为：通过粉碎程度等条件性实验可以确定具体的实验流程及参数,质谱可准确地测定页岩中各类气体的绝对含量,结果表明该方法可获得较好的重复性结果、较低的标准偏差。

This paper presents a method for determination of gas composition in shale by means of the combination of fragmentation and gas chromatography with mass spectrometry and chromatographic analysis. Research conclusion is： through the crushing degree of conditional experiments can determine the specific experimental process and parameters,the mass spectrometry can accurately determination the absolute content of all kinds of gas in the shale,results show that the method can obtain good reproducible results,low standard deviation.
