Method for identifying and processing reliable geochemical data of mud-polluted rock debris

The invention discloses a method for identifying and processing reliable geochemical data of mud-polluted rock debris, and relates to the technical field of geochemical testing of rock debris samples, F1, pollution data identification order correction, F2, pollution error determination, and F3, for a well without a pyrolysis spectrogram, the pollution amount is recursively calculated by using a pollution increasing rule, and two correction modes are summarized. According to the technical scheme, the method is suitable for rock debris samples polluted by solid powdery additives in water-based mud, samples of wells which are not polluted at the periphery are required to be compared to judge whether target well samples are polluted or not, rock core/well wall core samples must be used as standard samples, and pyrolysis spectrograms of part of the wells are compared with those of other wells to judge whether the target well samples are polluted or not. The TOC and S2 parameters of the polluted ...
