摘要： 以渤海B油田脱水原油与煤油的混合模拟油为油相,以聚合物表面活性剂(简称聚表剂)JBJ-1、JBJ-2或普通聚合物Pn溶液为水相,研究水油体积比为8∶2时形成的乳状液的稳定性能。结果表明,模拟油和聚表剂溶液形成的乳状液较稳定,黏度不是影响乳状液稳定的主要因素。同时考察了聚表剂质量浓度和水油体积比对乳状液稳定性的影响。结果表明,聚表剂质量浓度越大,乳状液越稳定;当JBJ-1质量浓度为0.2 g/L或JBJ-2质量浓度为0.2和0.4 g/L时,随着水油体积比的增加乳状液稳定性降低;在较高质量浓度(ρ(JBJ-1)>0.2 g/L或ρ(JBJ-2)>0.4 g/L)时,随着水油体积比的增加乳状液稳定性变好,破乳时间延迟,最大析水率增加。

Abstract: Stability performance of emulsion generated with simulated crude oil composed of dewatered crude oil from Bohai Oilfield Section B and kerosene as the oil phase and solution of polymer-surfactant JBJ-1,JBJ-2 or conventional polymer Pn as the water phase at the water-oil volume ratio of 8∶2 was examined.Results show that the emulsion generated with polymer-surfactant was comparatively more stable.Viscosity is not the main influencing factor of emulsion stability.The stability of emulsion was examined at different mass concentrations of polymer-surfactant solution and at different water-oil volume ratios.Results show that the emulsion stability improves with the increase of mass concentration of polymer-surfactant.For the same kind of polymer-surfactant,when the mass concentration of JBJ-1 at 0.2 g/L or JBJ-2 at 0.2 and 0.4 g/L,the emulsion stability decreases,but the emulsion stability becomes better at a higher mass concentration (ρ( JBJ-1)>0.2 g/L,or ρ(JBJ-2)>0.4 g/L) with the increase of water-oil volume ratio.The demulsification time delays and the maximum water decantation rate increases.

Key words: polymer-surfactant, emulsification performance, stability, viscosity
