摘　　要：油田生产产生的污油由于含硫化物固体颗粒易形成稳定的高导电性的油水黑色过渡层,导致电脱水器易垮电场,给采出液和采出水处理造成了很大危害,并已经成为油田生产中急待解决的难题。文章针对撬装式含硫化物污油机械处理成套装置进行改进和完善,同时选择机械处理装置-化学药剂法进行了某联合站的污油回收处理,不但解决回收处理污油对生产造成的危害,还实现污油的回收处理和改善电脱水器放水水质,同时减少污油排放产生的资源浪费和环境污染,确保脱水生产稳定运行。The solid particles contacting sulfide in the waste oil are prone to form stable and highly conductive oil-water black transition layer,and lead to the electric field collapse of the dehydrator.It has poses great challenge to the following treatment of produced water.In this paper,skid-type sulfide oily sludge treatment unit is improved and consummated.At the same time,a mechanical treatment device,combining with chemical agent method were selected to recover the waste oil from a joint station.This type of treatment could not only reduce the harm to oil production caused by the recovery and treatment of waste oil,but also realize the recovery and treatment of waste oil while improving discharged water quality from electric dehydrator.Furthermore,this type of treatment could reduce the resource waste and prevent environmental pollution caused by the discharge of waste oil,and ensure the stable operation of dehydration.
