| 摘 要： | 将采用分散聚合法制备的水包水乳液减阻剂直接溶解于纯水中,配制成滑溜水;通过环境扫描电子显微镜与室内管道摩阻仪对减阻剂进行微观结构表征与减阻性能测试。实验结果表明,该减阻剂具有良好的速溶性,能在 98 s 内溶解完全;减阻剂浓度和高价离子浓度影响滑溜水的减阻性能,其中,Ca^2+,Fe^3+,SO4^2-质量浓度分别超过 75,20,100 g/L 时,才会影响减阻效率;在滑溜水实际应用时应侧重非结构黏度的减阻作用。

| Abstract: | The water-in-water emulsion drag reducing agent prepared by dispersion polymerization was directly dissolved in pure water and made into slickwater. Microstructure characterization and drag reduction performance test were carried out by ESEM and indoor pipeline friction instrument.It was found that the drag reducing agent had good instant solubility and could dissolve within 98 s completely. The apparent viscosity and drag reduction efficiency of slickwater system were affected by the concentration of drag reducing agent and multi-charged ion. When the mass concentration of Ca2+,Fe3+,and SO42- exceeded 75,20,100 g/L respectively,drag reduction efficiency would be affected. |
