Abstract:

The high viscosity of heavy oil and studies the effect of construct and combination of oil-soluble viscosity reducer on viscosity reducing effect were discussed. The results show that unary-polymer has viscosity action and poor viscosity reducing effect, binary-polymer has definite raise and viscosity reducing rate exceeds 30% in 20 , terpolymer containing twain or more polar functional group researches has preferable effect and viscosity reducing rate is concordant with 70% in 20 , and advisable combination in difference viscosity reducer can display synergism and raise the viscosity reducing effect obviously.

Key words:

摘要: 分析了稠油高粘的本质, 研究了降粘剂的结构及复配对稠油降粘效果的影响。结果表明, 一元聚合物高温下具有增粘作用, 低温下具有微弱的降粘效果;二元聚合物的降粘效果有所提高, 20 ℃时的降粘率超过 30 %;含有2 种或2 种以上极性官能团的三元聚合物具有明显的降粘效果, 20 ℃时的降粘率接近70 %;不同降粘剂分子之间的合理复配可发挥分子间的协同效应, 明显提高降粘效果。
