【摘要】 本文采用碳氢类表面活性剂构建了高压CO₂/水乳液,用于可视化通道内的模拟油驱替实验。表面活性剂由聚醋酸乙烯酯（PVAc）和聚乙烯吡咯烷酮（PVP）通过RAFT反应合成。研究了该表面活性剂构建CO₂/水乳液的能力和驱替效率。结果表明,该表面活性剂构建的CO₂/水乳液稳定性好,在毛细通道内的驱替实验中表现出较高的波及效率,达到92.9%。相较于水驱（波及效率51%）和纯CO₂驱（波及效率45.8%）,CO₂/水乳液驱在毛细管中驱替有很大的优势。更多还原

【Abstract】 A hydrocarbon surfactant was synthesized by RAFT method,using Poly（vinyl acetate）and Polyvinyl Pyrrolidone,to emulsify CO₂ and water under high pressure,then the visual experiment of foam displacement was carried.The foaming ability and the foam displacement efficiency were studied.It was found that the foam remained stable and performed well in displacement with much higher swept efficiency（92.9%）,while water 51% and pure CO₂ 45.8%So,CO₂ foam displacement in the capillary channel has advantages.更多还原
