Research Progress in Stability of Oilfield Produced Water
Oil is called the blood of industry,and plays a very important role in the modern industrial system.A large amount of produced water will be produced in the process of oil exploitation,which is generally stable oil-water emulsion.This emulsion is extremely difficult to treat,which brings heavy environmental burden to oil exploitation.In order to improve the treatment effect of oil-water emulsion,a variety of research methods have been used to study the stability of oil-water emulsion.Through a lot of research,the influence path of crude oil components and chemical agents in oil-water emulsion on the stability of emulsion has been determined,and the stability mechanism of emulsion has made some progress.
