摘要
海拉尔盆地泥岩干酪根样品的13CNMR(CP/MAS和DD)谱分析表明,不同类型的未成熟干酪根,其芳族碳、氧接碳和脂族碳原子组成及结构参数存在明显差异,这些特征为研究干酪根的生物来源和生烃潜率提供了重要信息。随着成熟度增加(Ro为0.4%~1.1%),干酪根产油率减少,产气率增大,各类脂碳原子的组成分布随成熟度的变化揭示了干酪根的主要生烃产物和成烃时期。
An analyses of the mudstone kerogen samples from Hailar basin by using 13c NMR (CP / MAS and DD)techniques has demonstrated that the immature kerogens, affected by types of parent material, have significant differences in the composition and structural parameters in their aromatic carbons, aliphatic carbons and oxygen attached carbons. These characteristics provide an important information on organic precusor and potentials of generation hydrocarbon of kerogens. With increasing maturity (Ro 0.4%~ 1.1%), the potentials for hydrocarbon generation of kerogens are reduced and the potentials for gas generation of kerogens are increased. The change of composition distributions of aliphatic carbon atoms with maturity or maturation stage indicates. The principle products and hydrocarbon-generating period of herogens.
