摘　　要：采用含氢硅油与3种烯丙基聚氧乙烯聚氧丙烯醚进行反应,制备了混合聚醚改性聚硅氧烷共聚物,以二甲苯为溶剂配制成溶质质量分数20%的溶液作为破乳剂,用于渤海油田稠油的破乳脱水。与平台现场在用破乳剂相比,采用自制破乳剂时脱出的污水水色略差,但破乳脱水速度更快。该自制破乳剂用于100 mL含水量10%和60%油样时,40 min的脱水体积不低于8 mL和53 mL,脱水界面齐整,有望作为一款用于渤海稠油油田现场的新型破乳剂,具备深入研究的价值。The copolymer of the mixed polyether modified polysiloxane was prepared by hydrogen-containing silicone oil and three types of allyl polyoxyethylene polyoxyel ether.The solution with xylene mass fraction of 20%was prepared and used for demulsification and dehydration of heavy oil in Bohai oilfield.Compared with the demulsifier in use on the platform,the color of the effluent was slightly worse when the self-made homemade demulsifier was used,but the dehydration speed was faster.When the demulsifier was used in 100 mL oil with water content of 10%and 60%,the dehydration volume in 40 minutes is not less than 8 mL and 53 mL,and the dehydration interface is smooth.The new demulsifier is expected to be used as a new demulsifier in Bohai heavy oil field,and worth further study.
