As a high molecular organic polymer, polyacrylamide has excellent water solubility, and can be said to be one of the most widely used water-soluble polymer compounds. In oilfield flooding and oilfield exploitation, partially hydrolyzed polyacrylamide, or PHPA for short, is the most commonly used. Practice has proved that the use of PHPA as a polymer oil-displacing agent has a very obvious effect on enhanced oil recovery (EOR), and has become a crucial part of the production of some mid-late oilfields.
The cross-linking system of partially hydrolyzed polyacrylamide is widely used in oil fields. The types and proportions of cross-linking agents, the molecular weight and degree of hydrolysis of PHPA, the viscosity of the cross-linking system, the gelation time, the gel strength and stability, the There are a lot of studies at home and abroad in terms of glue methods, etc. The polymer concentration in the PHPA cross-linked system used in adjustment, water plugging, fracturing, sand control, etc. is relatively high, generally reaching 1000 mg/L or more.
The PHPA produced by Qingdao Oubo Chemical Co., Ltd. has been used well in oil fields such as Chile, India and Argentina, or has attracted wide attention from the international market. Welcome to consult.
