| 中文摘要 | Gaseous hydrocarbon geochemistry research through a thermal simulation experiment in combination with the natural evolution process in which natural gases were formed from coal-measure source rocks revealed that the δ13C1 values of methane vary from light to heavy along with the increase of thermal evolution degree of coal-measure source rocks， and the δ13C2 values of ethane range from -28.3‰ to -20‰(PDB). δ13C2 value was -28‰± (Ro=0.45%-0.65%) at the lower thermal evolution stage of coal-measure source rocks. After the rocks entered the main hydrocarbon-generating stage (Ro=0.65%-1.50%)， δ13C2 values generally varied within the range of -26‰--23‰±; with further thermal evolution of the rocks the carbon isotopes of ethane became heavier and heavier， but generally less than -20‰; The partial carbon isotope sequence inversion of hydrogen gases is a characteristic feature of mixing of natural gases of different origins. Under the condition of specially design. |
