油田聚丙烯酰胺 Oil Field Polyacrylamide
Oilfield additive polyacrylamide is a multi-functional additive. It is used in mud conditioning agent, stabilizer and sedimentation flocculation in oil field drilling process to improve mud rheology. It can improve the size of suspended particles, increase suspension force and accelerate the filtration and separation of crude oil. As a soil structure shaping agent, the anti-impact performance of the wellbore surface is improved, and the non-dispersible slurry can be separated efficiently when drilling through the opening of the formation. Hydroxymethylation of partial hydrolyzed homogeneous polyacrylamide with formaldehyde and glyoxal to produce side chain methyl-containing products can achieve satisfactory results in crude oil production.
