The relationship bet ween viscosity and saturate,aromatic compounds of 21 oil samples in Leng43/37 blocks,Liaohe Oil Field was studied based on TLC- FI Danalysis and solvent selective extracting-Cuantitatively 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 bet ween viscosity and aromatic compounds shows a changing trend with viscosity. Aseries of models were primarily constructed to predict the viscosity of biodegraded oil in this paper.
