| 英文摘要 | Pyrobitumen, considered a carbon-rich solid product of oil thermal cracking, widely exists in oil/gas source rocks and reservoirs. The importance of the polar fractions on the formation of pyrobitumen has been acknowledged. However, the precise role of the polar fractions in the formation of pyrobitumen is still not well understood. Since the heteroatoms of nitrogen (N), oxygen (O) and sulfur (S) mainly exist in the polar fractions, the investigation of their content and evolution characteristics during the formation of pyrobitumen will provide an understanding of the formation mechanism of pyrobitumen. In this study, laboratory pyrolysis experiments on three types of oil (normal oil, light oil and heavy oil) were conducted. The major pyrolysis products, such as gaseous compounds, liquid fractions and pyrobitumen, were quantitatively analyzed. The elemental compositions of carbon (C), hydrogen (H), O, N and S in the obtained liquid products and pyrobitumen were measured. From the yields of the pyrolysis products and the determined elemental compositions, we propose a three-stage formation scheme for pyrobitumen. In the first stage, the reactions are dominated by a cross-linkage of the polar fractions in crude oil that occurs at an Easy Ro>1.0% (H/C for pyrobitumen 1.4–1.6% (H/C for pyrobitumen 4 at an Easy Ro>3.0% (H/C for pyrobitumen ? 2023 Elsevier Ltd |
