摘　　要：用聚丙二醇和甲苯二异氰酸酯为原料,二甲苯为溶剂合成了聚氨酯型原油破乳剂(PPG)。对不同含水率的油水乳状液及原油进行了破乳试验,选出了最佳用量。结果表明PPG对原油的适应性强,破乳速度快,用量低。Polyurethane demilsifiers for crude oil were prepared from polypropylene glycol, xylene, toluenediiso-cynate in xylene solvent. Demulsifing tests on different water content oil water emulsion and crude oil were performed. The best concentration of demilsifiers were selected. Results indicate that PPG can be used in dif-ferent kinds of crude oil and demulsifing was fast in low concentration.
