A time series of produced shale gas samples from different blocks in Sichuan Basin, China were collected during 4 years period of shale gas production from year 2014‒2018. On the basis of molecular composition, stable carbon and hydrogen isotopic data analyses by an integrated method of gas chromatography combined with mass spectrometry, the shale gas geochemical features from different blocks were comparatively studied. Moreover, shale gas genesis and carbon isotopic reversal causation were discussed as well.
