摘　　要：研究了分子量大小、减阻剂浓度、温度、矿化度以及p H值对非离子聚丙烯酰胺减阻性能的影响。结果表明,在低加量条件下(小于0.1%),不同分子量的非离子聚丙烯酰胺的减阻性能相差不大,非离子聚丙烯酰胺的浓度越大减阻性能越好;有一定的抗温性能,抗温临界点为65℃;钙离子对其减阻性能有一定的影响,钙离子越高减阻性能越低,提高减阻剂浓度能提高抗钙能力;碱性环境对非离子聚丙烯酰胺的减阻性能影响很小,几乎没有影响,酸性环境对其减阻性能影响很大,酸性越强,减阻性能越差。The effect of molecular weight, drag reducing agent concentration, temperature, salinity and pH value on the drag reducing properties of nonionic polyacrylamide was studied. The results showed that the molecular weight of non-ionic polyacrylamide had little effect on its drag reduction performance at low dosage, and the higher the concentration of non-ionic polyacrylamide, the better the drag reduction performance; it had a certain temperature resistance, the critical temperature resistance point was 65 ℃; calcium ion had a certain effect on its drag reduction performance, the higher the calcium ion concentration, the worse the drag reduction performance. Increasing drag reducing agent concentration could improve the calcium resistance; alkaline environment had little effect on the drag reduction performance of non-ionic polyacrylamide,while acid environment had a great impact on its drag reduction performance, the stronger the acidity, the worse the drag reduction performance.
