The aim of this work is to investigate the solid bitumens generated at different thermal maturity levels by oil cracking simulation experiment and Laser Raman spectroscopy analysis. The results indicate that, with the maturity increasing, D-peak position in the Raman spectra of solid bitumens shifts towards lower wavenumber
