摘　　要：用模拟碱／聚合物二元复合驱采出液，以脱出水色为主要评价项目，对新开发的若干系列的破乳剂＋净水剂复配物的破乳性能进行了室内评价。聚丙烯酰胺含量最高达１１６０ｍｇ／ｌ、碳酸钠含量最高达８０００ｍｇ／ｌ的模拟采出液破乳实验结果表明，聚合物含量是影响破乳效果的主要因素。破乳性能最好的破乳剂是ＡＥＤ７８和ＡＥＤ２３（甲苯二异氰酸酯扩链的双嵌段聚醚），净水剂是ＱＢＳ０５（阳离子苄基淀粉）和ＱＳ０６（阳离子淀粉）。Several series of newly developed demulsifiers and water clarifying agents in combination are evaluated for demulsifying simulated produced fluids from alkaline/polymer flooded reservoirs according mainly to the appearance of the water separated. The polymer content in the produced fluids is shown to be the basic influencing factor in demulsifying simulaled fluids containing HPAM up to 1160 ppm and sodium carbonate up to 8000 ppm. The best demulsifiers selected out are AED 78 and AED 23, TDI chain extended diblock polyethers and the best water clarifying agents-QBS 05, a cationized benzylstarch, and QS 06, a cationized starch.
