采用催化加氢热解技术提取了高演化沉积有机质中共价键结合生物标志物分子。催化加氢热解是在高氢压(>10MPa)、较慢的升温速率(5℃min)和高分散型催化剂作用下的还原反应,是一种对提取高收率、少结构重排的干酪根和沥青质分子骨架中共价键结合的生物标志化合物有独特作用的分析性手段。实验结果表明,通过催化加氢热解处理可以合理释放出高演化沉积有机质分子骨架中的具有原生性的组分,在油油对比、油源对比、油藏有机质沉积环境以及油藏的次生改造等研究方面可获得较好的应用。特别是针对高演化沉积物和一些后期严重降解的油藏而言,在恢复原始有机地球化学信息研究方面更具有重要意义。
Catalytic hydropyrolysis was used to extract covalently bound biomarkers in highly-evolved sedimentary organic matter. Catalytic hydropyrolysis is a reduction reaction under high hydrogen pressure (> 10MPa), slower heating rate (5 ℃ min) and high dispersion type catalyst. It is a kind of reduction reaction with high yield and less rearrangement Kinematic and asphaltene molecular framework of the covalent bond biomarker compounds have a unique analytical means. The experimental results show that the composition of protoplasm in the framework of highly evolved sedimentary organic matter can be reasonably released by the catalytic hydropyrolysis process. In the comparison of oil and oil, the comparison of oil sources, the depositional environment of organic matter in reservoirs and the secondary Transformation and other research can get a better application. Especially for the highly evolved sediments and some seriously degraded reservoirs in later stage, it is more important to restore the original organic geochemical information research.
