摘　　要：稠油中含大量胶质沥青质等重质组分使得稠油流动性减弱,黏度增加。以油脂为原料,采用常压水解制备了一种油溶性降黏剂,利用傅里叶红外光谱、核磁共振氢谱、元素分析、能谱分析、热重分析以及气相色谱–质谱分析对产物进行了结构表征。实验考察了降黏剂的降黏性能和腐蚀性能,确定了合成产物的降黏效果优于现场在用的降黏剂样品。Heavy oil contained a large amount of heavy components such as colloidal asphaltene, which weakened the fluidity of the heavy oil and increased the viscosity. In this paper, an oil-soluble viscosity-reducing agent was prepared by using oil as raw material, and the product was analyzed by Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, elemental analysis, energy spectrum analysis, thermo gravimetric analysis and gas chromatography-mass spectrometry, a series of structural characterizations were performed. The experiments examine the viscosity-reducing properties and corrosion properties of the viscosity-reducing agent, and it is determined that the viscosity-reducing effect of the synthetic product is better than the viscosity-reducing sample in the field.
