| 摘 要： | 清水剂是处理油田聚驱后产生的含有残余聚合物的含油污水（含聚污水）的重要添加剂，不同类型清水剂实现含聚污水油、水分离的作用过程不尽相同。以3种不同类型清水剂（阳离子型、两性离子型和非离子型）为研究对象，利用液滴聚并法研究了在不同温度和清水剂添加量下模拟残余聚合物水溶液中清水剂对不同原油组分界面稳定性的影响，并结合界面张力结果分析了原因。结果表明：阳离子清水剂主要与沥青质作用促进水中油滴聚并，两性离子清水剂主要与胶质和沥青质作用促进水中油滴聚并，非离子清水剂与原油中4种组分均可作用促进油滴聚并。

| Abstract: | Clarifying agent is an important agent to treat the wastewater produced from the polymer flooding in oil field (it containing residual polymers) and different type of clarifying agent realizes different oil water separation processes. Three kinds of clarifying agents (cationic, amphoteric ionic, non ionic) were used to research their effects on interfacial stability of various component of crude oil considering different conditions of temperature and dosage by simulating the residual polymers solution and coalescence method. The reasons were analyzed briefly combining with the result of interfacial tension. The experimental results demonstrated that the cationic clarifying agent interact with the asphaltene primarily and accelerating the coalescence process. The amphoteric ionic clarifying agent mainly react with the resin and asphaltene, and the non ionic clarifying agent can interact with four kinds of component of the crude oil and facilitating the process. |
