Polyaluminium Chloride and Polyacrylamide Serve as Oilfield Chemicals
High-purity polyaluminium chloride is mostly applicable to the purification of petroleum in petroleum exploitation process. Polyacrylamide is mainly used in the drilling mud materials, and also it can increase the oil recovery rate.
As a commonly used oil drilling chemicals, polyacrylamide is widely applied in various oilfield exploitation processes including the well drilling, well completion, well cementation, fracture, and the intensified oil production, etc. It provides different functions such as tackifying, filtrate reduction, rheology adjustment, jelling, bypass, cross-section adjustment, and more.
