When oil fields are in EOR periods, feeding a ton of polymer can increase the production of crude oil by 120 ~ 150 tons for users.By injecting polymer solution with suitable viscosity,it can improve the sweep efficiency of injected fluid,and thus block big channels.Our products have already been widely used in oilfields like in Daqing, Shengli, Dagang, Liaohe, Xinjiang, Henan, North America, South America, India, the Middle East, Russia and other fields.
Ordinary product can resist a temperature up to 75℃ and a salinity up to 30000 ppm. Salt-tolerant products can resist a temperature up to 90℃ and a salinity up to 30000 ppm.
