摘要: 在对两个褐煤样品进行生烃和排烃模拟实验的基础上,研究了其芳烃产物的特征.结果表明:与生物分子有相同位取代(甲)基的芳烃化合物是由非芳烃形成芳烃的主要中介产物,因此芳烃演化的主要趋势可能是脱甲基作用而不是甲基化作用;许多芳烃比值是敏感的成熟度指标;烷基取代芳烃较对应的无取代芳烃难以运移.因此,有关比值具有作运移指标的潜力.

Abstract: Based on data acquired from pressurized thermal simulation experiments in which both hydrocarbon generation and expulsion from two brown coals are inspected,the characteristics of aromatic products are studied in this paper.The results indicate:(1)The aromatic compounds bearing substituting groups at the same position as the corresponding biomolecule are the main intermediate products of forming various aromatic compounds from non-aromatic compounds.The dominant evoluationary trend of aromatic compound may be demethylation rather than methylation.(2)A lot of aromatic parameters are sensitive maturation indexes.(3)The substituted aromatic compounds are more difficulty to migration than their corresponding non-substituted aromatics.Therefore, the relevant ratios have the potential to act as migration parameters.
