油田聚丙烯酰胺 Oil Field Polyacrylamide

油田助剂聚丙烯酰胺,它是一种多功能添加剂.在油田钻井工艺中用于泥浆的增调剂、稳定剂和沉降絮凝制以改进泥浆的流变性;能改进悬浮颗粒的大小,提高悬浮力,加速原油的过滤、分离。作为土壤结构成型剂,使井壁表面抗冲击性能提高,钻井通过启层时使不易分散的液浆获得高效的分离效果。使部分水解均聚丙烯酰胺与甲醛、乙二醛等发生羟甲基化反应而生成侧链含甲基的产物,在原油生产中可获得满意的效果。

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.
