摘要
松辽盆地原油核磁共振(NMR)谱的分布特征表明,原油可划分为四种类型。原油平均分子结构参数(C_(Ar)、C_N、Cp,H_Ar、H_N、H_p,CH、CH_2、CH_3)反映了松辽盆地原油由腐殖型和腐泥型(或腐殖腐泥型)干酪根生成。随成熟度增加,原油的芳碳(C_(Ar))结构减少;多环烷烃向链烷烃和单环烷烃转化,表现为环烷次甲基碳(CH_(1-2))含量降低;链烷碳(C_P)和链烷次甲基碳(CH_(1-1))含量有增大趋势。 这些结构演化特征为研究原油的成熟度提供了有益的信息。
According to its 1H and 13C NMR spectrum crude oil from the Songliao Basin can be roughly divided into four types and five subtypes. The average structural parameters indicate that the crude oil was generated from both sapropelic kerogen and humic kerogen. The relationship between structural parameter and maturity is also discussed in this paper.
