RESEARCH PROGRESS ON TREATMENT TECHNOLOGY OF REFRACTORY POLYMER-CONTAINING OILFIELD PRODUCED WATER

Produced water containing polymer has the characteristics of complex water quality, high viscosity, high degree of emulsification, and high oil content, which causes difficulty in oil-water separation and has serious impacts on oilfield production operations and the environment. This study analyzed the water quality characteristics of the polymer-containing produced water, and summarized the treatment technologies of the polymer-containing produced water, such as membrane separation method, air flotation method, advanced oxidation method, microbial method, etc., and explained the application of these treatment processes in various oil fields. The advantages and problems of various treatment technologies were described. This study also introduced the treatment technologies of polymer-containing produced water and the development of skid-mounted integrated water treatment equipment. Finally, some prospects were put forward for future research of polymer-containing produced water treatment technology, hoping to provide reference for the researches and engineering application of the sewage treatment technology.
