Аннотация:The paper presents the results of thermodynamic modeling of a transformation of a kerogen-bearing sedimentary rock within the temperature range of 50-400 degrees C at a gradually increasing pressure from 300 to 2200 bar. A gradual increase in temperature and pressure, starting from 50 degrees C, leads to the formation of the lighter and more oxidized type of kerogen. The methane-carbon dioxide gas phase is present in the entire range of specified temperatures and pressures. The coexistence of kerogen and oil was obtained only in one calculation for 325 degrees C and 1750 bar. In the presence of kerogen in the system, the oil consists of 92% alkane hydrocarbons. With a further increase in temperature, the kerogen disappears and a share of aromatic hydrocarbons in oil rises to 49-77%.
