Abstract
To solve the problem of high viscosity and poor fluidity of Xinjiang heavy oil,the polyesterseries MAS oil-soluble viscosity reducer with phenyl group and amide bond was synthesized and characterized by Fourier Transform Infrared Spectrometer(FTIR). The effectiveness of the viscosity reducer on Xinjiang heavy oil was evaluated. The results showed that MAS5 with main chain of ethyl acetate and MAS4 with long main chain alkyl acrylate(C18) performed better in viscosity reduction on heavy oil. The amide bond in MAS5 can interact with the resin and asphaltene inheavy oil,and the benzene ring can affectπ-π force between the polycyclic aromatic molecules,and the ethyl acetate can form the solvation layer around the asphaltene aggregate to reduce further aggregation of the asphaltene molecules,all of these resulting in the viscosity decrease ofheavy oil. The synthesis conditions for MAS5 were optimized. When the dosages of MAS5 viscosity reducer in Xinjiang heavy oil are 600mg/L and 1000mg/L,the corresponding rates of viscosity reduction were 50.6% and 53.7%,respectively at 50℃. Furthermore,the price of raw materials for MAS5 is lower so it has a better prospect for industrial applications.关键词
