| Fig. 12. Occurrence state of retained hydrocarbons in lacustrine organic-rich shale. (a) Ordos Basin, Well L147, Chang-7 Member, TOC = 11.9%, the retained hydrocarbons are adsorbed on the pyrite intercrystalline pores and surface; (b) Ordos Basin, Well L251, Chang-7 Member, TOC=8.5%, the retained hydrocarbons are adsorbed on the surface of organic matter; (c) Junggar Basin, Well J174, Lucaogou Formation, TOC=3.6%, the retained hydrocarbons exist in the intergranular pores of albite and dolomite in a free state |
