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.

Polyacrylamide (PAM) is a general term of acrylamide homopolymer or polymer copolymerized with other monomers. It is one of the most widely used varieties in water-soluble polymers. Because the structural unit of polyacrylamide contains amide group and is easy to form hydrogen bond, it has good water solubility and high chemical activity. It is easy to obtain a variety of modifiers with branched chain or network structure through grafting or cross-linking. It is widely used in petroleum exploitation, water treatment, textile, papermaking, beneficiation, medicine, agriculture and other industries, and is known as "Baiye assistant". The main application fields abroad are water treatment, papermaking, mining, metallurgy, etc; At present, the largest consumption in China is in the field of oil production, and the fastest growth is in the field of water treatment and papermaking.
