摘要: 三元复合驱采出水(ASP-PW)处理的油水分离问题已经成为了三元复合驱技术推广的技术瓶颈。本文采用超声波强化聚合氯化铝(PAC)协同处理ASP-PW的方法，大大提高了油水分离效果。通过实验研究发现，在超声频率40 kHz、超声时长为60 min时，乳化油滴粒径由349 nm增大到3639 nm，表明了超声对乳化油滴起到了一定的凝聚作用；当超声与PAC协同处理ASP-PW时，在超声时长为60 min、加药量为850 mg∙L⁻¹，并于40 °C恒温水浴中沉降30 min，其除油率高达95.82%，远高于相同条件下单独使用超声的除油率(86.12%)和PAC的除油率(90.87%)，协同作用效果显著。实验内容接地气，是科教融合的重要体现，实验方法遵循绿色可持续发展的理念，实验过程锻炼了学生自主探究能力。该实验从问题调研、方案设计到结果的获取均凸显出团队协作的关键作用，本实验也为ASP-PW的处理提供新的方向。

Abstract: he issue of oil-water separation in the treatment of produced water by ternary composite flooding (ASP-PW) has emerged as a technical bottleneck in the widespread adoption of ternary composite flooding technology. This paper introduces a method that utilizes ultrasonic-enhanced polymeric aluminum chloride (PAC) for the synergistic treatment of ASP-PW, significantly improving the efficiency of oil-water separation. Experimental findings reveal that, at an ultrasound frequency of 40 kHz and a duration of 60 min, the particle size of emulsified oil droplets increased from 349 nm to 3639 nm, indicating the consolidating effect of ultrasound on emulsified oil droplets. When ultrasonic and PAC are employed in tandem to process ASP-PW, with ultrasound duration at 60 min, dosage at 850 mg∙L⁻¹, and a settling time of 30 min in a 40°C water bath, the oil removal rate reached 95.82%. This rate surpasses the individual oil removal rates of ultrasound alone (86.12%) and PAC (90.87%) under the same conditions, demonstrating a significant synergistic effect. The experiment’s practical content is a crucial manifestation of science and education integration. Following the principles of green and sustainable development, the experimental process enhances students’ ability for independent exploration. This experiment, spanning from problem investigation and program design to result acquisition, underscores the pivotal role of teamwork. Additionally, it opens up new possibilities for the processing of ASP-PW.
