两种聚合物表面活性剂与渤海B油田原油乳化性能研究
发布时间：2019-04-29 20:54
【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]:The mixed simulated oil of dewatered crude oil and kerosene in Bohai B oilfield is used as the oil phase, and the polymer surfactant (JBJ-1,JBJ-2) or the ordinary polymer Pn solution as the aqueous phase. The stability of emulsion was studied when the volume ratio of water to oil was 8: 2. The results show that the emulsion formed by simulated oil and polymer solution is stable, and the viscosity is not the main factor affecting the emulsion stability. At the same time, the effects of the mass concentration of polymer and the volume ratio of water to oil on the stability of emulsion were investigated. The results showed that when the mass concentration of JBJ-1 or JBJ-2 was 0.2g / L and 0.4g / L, the emulsion stability decreased with the increase of the volume ratio of water to oil. At higher mass concentration (蟻 (JBJ-1) 0.2g / L or 蟻 (JBJ-2) 0.4g / L), the emulsion stability becomes better, the demulsification time is delayed and the maximum water evolution rate increases with the increase of the volume ratio of water to oil.
