Fig.4 δ13c1-drying values of multi-well reservoir in fault in BD21(The carbon isotope and component data of Songtao bulge,Songnan Sag, Songnan low bulge and Lingshui sag were obtained from natural gas production, and the data were cited from references [7], [8], [13], [21]. Other data are derived from isotopic logging and are all carbon isotope data of mud gas while drilling. Same as in Fig.5)
