Abstract：With the method of field desorption and gas chromatography, the components content correction of shale gas with low desorption gas quantity was studied. Correction experiment was added besides normal field desorption experiments, and ideal gas state equation was also used to seek the correction parameters and their suitability. The results showed that the residual air within the desorption canister had a great effect on components content when desorption gas content is low. Volume fraction of methane will increase about 12.23%-54.44% generally if the residual air can be excluded. It is thus necessary that the components content of shale gas with low desorption gas quantity should be corrected.
