摘要
沥青质分子骨架中吸附、包裹了一些烃类组分,这些组分较少受到油藏后期演化的改造,被认为具有原生性,包含有重要的有机地球化学信息。实验结果表明,通过轻度化学氧化降解处理可以合理释放出沥青质分子骨架中这些具有原生性的组分,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应用;特别是针对一些遭受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。
Some hydrocarbon components adsorbed and included in the molecular skeleton of asphaltene. were subjected less reconstruction from the paulopost evolution of oil pools, and were thought to be primary and containing important organic geochemical information. The experimental results showed that these primary components in the molecular skeleton of asphaltene can be released rationally by mild chemical oxidation degradation treatment, and can obtained well application in oiloil correlation, oilsource correlation, the sedimentary environments of organic matter in oil pools, the secondary reconstruction of oil pools and other researches. To some oil pools subjected serious paulopost degradation, these components especially possessed important significance in the study of restoring original organic geochemical information.
