Thermal cracking for upgrading medium-low maturity shale oil: evolution of organic matter occurrence.

ABSTRACT: The evaluation of the basic properties and hydrocarbon generation potential of medium-low maturity shale oil serves as a critical link between geological resources and engineering development. This study focuses on JY oil shale, utilizing analytical techniques including vitrinite reflectance (R₀), total organic carbon (TOC), thermogravimetric analysis (TGA), and Rock-Eval pyrolysis to systematically characterize its geochemical properties. Based on sample characteristics, an in-situ upgrading simulation system was developed and optimized. By comparing nuclear magnetic resonance (NMR) T₁-T₂ spectrum and pyrolysis-gas chromatography/mass spectrometry (PY-GC-MS) results before and after thermal cracking, the research further elucidates the mechanism by which t
