A set of thick, black organic shale is developed at the bottom of the Chang 7 accumulation, an important oil-producing section of the Triassic Yanchang Formation in Ordos Basin. In this paper, the thermogravimetric (TG) behaviour of different organic-rich shale layers is studied in an argon environment. Changes in activation energy (E) are analysed by the Coats-Redfern kinetic method, and thermodynamic characteristics at different temperature stages are clarified. The TG curve of Chang 7 shale d...
