【摘要】 利用薄层色谱—氢火焰离子检测和溶剂选择抽提—定量GC/MS分析技术 ,对辽河油田冷 43/ 37断块区 2 1个原油样品进行了粘度与饱和烃、芳烃化合物相关性研究。结果发现原油粘度随饱和烃族组成含量降低而升高 ,与芳烃族组成无关 ,但与萘、菲、二苯并噻吩系列芳烃化合物的绝对浓度及其在总芳烃中的百分含量关系密切。就不同粘度范围的原油 ,其芳烃化合物参数与粘度的相关性亦不尽相同。文中还初步建立了适应不同粘度范围的一系列粘度预测模型更多还原

【Abstract】 The relationship between viscosity and saturate, aromatic compounds of 21 oil samples in Leng43/37 blocks, Liaohe Oil Field was studied based on TLC-FID analysis and solvent selective extracting-quantitatively GC/MS analysis. Oil viscosity increases while saturate bulk composition decreases. Moreover, oil viscosity has close relationship with the absolute concentrate of naphthalene, phenanthrene and dibenzothiophene compounds and their percentage in aromatics rather than aromatic gross composition. The relationship between viscosity and aromatic compounds shows a changing trend with viscosity. A series of models were primarily constructed to predict the viscosity of biodegraded oil in this paper.更多还原
