Abstract:

The effect of the compound system of IAEC?1306H (Isotridecyl alcohol polyoxyethylene ether carboxylic acid solution), alcohol solution and alkali agent on the viscosity of heavy oil was studied. The results show that under the same mass fraction conditions, maltitol has better viscosity?reducing effect on heavy oil than sorbitol, and NH₃·H₂O water has better viscosity?reducing effect on heavy oil than IAEC?1306H and alcohol solution.The mmonia water and IAEC?1306H have similar on the viscosity reduction effect of on heavy oil.With the increase of the volume fraction of NH₃·H₂O and the mass fraction of IAEC?1306H, the viscosity of the heavy oil gradually stabilizes.In the binary compound system, the binary system formed by compounding sorbitol and maltitol with IAEC?1306H respectively has the same viscosity reducing effect on heavy oil. And due to the nature of the alkali agent, the compounding of the alkali agent and IAEC?1306H is more conducive to the viscosity reduction of heavy oil.In the ternary compound system, the ternary system formed by the combination of NH₃·H₂O, maltitol and IAEC?1306H has a better viscosity?reducing effect on heavy oil, with a viscosity?reducing rate of more than 96%, and the dosage of NH₃·H₂O, IAEC?1306H, and maltitol are used less.

摘要：

研究了IAEC?1306H（异构十三醇聚氧乙烯醚羧酸）与醇溶液和碱剂的复配体系对稠油黏度的影响。结果表明，在质量分数相同的条件下，麦芽糖醇对稠油的降黏效果优于山梨糖醇，NH₃·H₂O对稠油的降黏效果优于IAEC?1306H和醇溶液；NH₃·H₂O和IAEC?1306H对稠油的降黏效果相似，随着NH₃·H₂O体积分数和IAEC?1306H质量分数的增加，稠油黏度逐渐趋于平稳；山梨糖醇、麦芽糖醇分别与IAEC?1306H复配形成的二元体系，对稠油的降黏效果基本一致，并且由于碱剂自身的性质，碱剂与IAEC?1306H复配更有利于稠油的降黏；NH₃·H₂O、麦芽糖醇与IAEC?1306H复配形成的三元体系，对稠油的降黏效果较好，降黏率达到96%以上，而且NH₃·H₂O、IAEC?1306H、麦芽糖醇用量较少。
