用于净化油田污水絮凝剂与缓蚀剂协同作用的研究

STUDY ON THE SYNERGISM OF FLOCCULATION/CORROSION INHIBITION FOR PURIFYING OILFIELD WASTE WATER

对ＰＡＭ，ＰＡＣｓ．ＰＡＣ＋ＣＧ－Ａ和ＨＱＪ－８７四种絮凝剂进行了一系列条件实验，系统地考察了絮凝剂的用量、搅拌时间、ｐＨ值及温度等各因素对净化含油污水效果的影响，并针对大庆油田注水系统腐蚀严重的状况进行了繁凝缓蚀协同作用的研究，为解决油田的实际问题提供了可行的技术。

Abstract A series of conditional experiments with PAM,PACS,PAC+CG-A and HQJ-87has been done.The factors influencing the purification of oilfield waste water were stud-ied experimentally,including the pH value,the stirring time,the temperature and theconcentration of the floccuiant added.In accordance with serious corrosion of waterflooding system of Daqing Oilfield,the synergism of flocculation/corrosion inhibitionwas examined,too.It has been proved a practicable technology for settling practicaloroblems in the Oilfield。SUBJECT TERMS:flocculant,corrosion inhibitor
