摘　　要：针对渤海某油田污水开展了聚二甲基二烯丙基氯化铵类(PDDA)清水剂的分析实验,结果表明:针对该油田污水,PDDA类清水剂能起到良好的清水剂效果,注入浓度随清水剂分子量的增加而减小;随着清水剂分子量的增加,产生的污油粘度增大,同时对原油脱水效果的影响也显著增强;只有分子量在合理区间才能满足在达到一定清水效果的同时对原油脱水效果无影响的目标。Carrying out the study of the water clarifier of PDDA of Bohai oilfield,the outcome showed that the PDDA can effect well to deal with the production water,the concentration of the waiter clarifier was decreasing while the molecular weight was increasing,the viscosity of the waste oil was increasing when the concentration of the PDDA was increasing or the molecular weight was increasing,when the molecular weight was between some range,the water treatment goal could be reached and the dehydration of the oil wouldn't be effected.
