辽河特稠油降粘研究

Study on the Viscosity Reduction of Liaohe Extra-Viscous Crude Oil

对辽河特稠油的组成和物性进行了分析 ,分析结果表明 ,胶质含量高是辽河冷东特稠油粘度高、流动性差的主要原因 ,研制能在较高温度区高效降粘的改质胶质油溶性降粘剂是解决该类油品输送问题的可行性方案 ,通过试验 ,初步探索了降粘剂的组成及分子量分布对其降粘性能的影响。

The analysis on the composition and physical characteristics of Liaohe extra-viscous crude oil is made.The results show that the high gum content makes this kind of oil difficult to flow. It is considered that the best way to transport this oil is to develop an oil-soluble viscosity reducing agent to restructure the gum and reduce viscosity efficiently at higher temperature. The trial test on the influence of composition and distribution of molecular weight of viscosity reducing agent on viscosity reducing behavior is made.l,pipelinet
