英文摘要In order to understand the influence of source rock types and maturity on hydrocarbon gases carbon isotope change more objectively, a closed-system pyrolysis experiment was carried out on six samples from 250 to 550 degrees C. The values of delta C-13(1), delta C-13(2), and delta C-13(3) were ranged from -73.3 to -29.8%, from -36.3 to -9.5%, and from -38.5 to -12.4%, respectively. The range of delta C-13(1) was the largest, reaching a top value of 43.5%. The results showed that the temperature has an effect on the carbon isotope value of pyrolysis gas. With the increase of the degree of thermal evolution, the carbon isotope value of methane in all samples, except for huangxian gangue, had a change trend from heavy to light firstly, then got heavier. In addition, the carbon isotope values of methane, ethane and propane had the features of delta C-13(1) < delta C-13(2) < delta C-13(3) when the temperatures were under 550 degrees C, which were made up of a series of positive carbon isotopes. However, when the temperature increased above 550 degrees C, there was an inversion of the simulated gas carbon isotope values in Huangxian coal gangue, Minqin oil shale and Huaan carbonaceous shale, i.e., delta C-13(2) > delta C-13(3) and delta C-13(2) > delta(1)3C(1). It indicates that the secondary cracking has occurred at high maturity or over maturity stage.
