摘要
通过室内实验,研究了单一碱、单一表面活性剂及复合驱体系与原油间的乳化现象,及影响乳状液的类型、稳定性的因素。结果表明,0.2%BES+0.1%SLPS+Na_2CO_3复合驱体系中,Na_2CO_3加量为0.5%时,乳状液粘度较低,形成 O/W 型乳状液;并且,在此 O/W 型乳状液中加入聚合物 HPAM 后,乳状液稳定性大大增加。
The emulsification states of crude oil with individual alkaline,surfactant or combination flooding systems and the factors influencing the types and stability of the formed emulsions were studied by lab experi- ments.The results showed that the low viscosity O/W emulsion was formed when the content of Na_2CO_3 was 0.5% in the combination flooding system (0.2% BES +0.1% SLPS + Na_2CO_3),and that the stability of the O/W emulsion was significantly improved after adding HPAM polymer in it.
