摘　　要：概述了国外减阻剂在减阻机理和生产工艺等方面的最新研究成果。研究结果表明,本体聚合可以大大提高减阻聚合物的分子量;溶液聚台在提高聚α-烯烃分子量、改善分子量分布等方面也有了新的突破。在聚合的后处理方面、分析了现广泛应用于原油管道和成品油管道上的水基乳胶状减阻剂和低粘度胶状减阻剂的特性。介绍了最近研究开发的一种非水基悬浮减阻剂,该剂克服了以前各种减阻剂的缺陷,可同时应用于原油和成品油管道。指出微囊减阻剂是一个新的发展方向。The latest achievements in study related to DRA's drag reducing mechanism and DRA production at abroad are described in the paper. The current study results have shown that a higher molecular weight of α-olefin polymer can be obtained through bulk polymerization, and the development in solution polymerization improving the distribution of molecular weight has been made. The behaviors of nonaqueous drag reducing suspensions and nonaqueous jel DRA that are currently being used in crude/product pipeline are introduced related to the post-treatment of polymer. The nonaqueous drag reducing suspensions recently developed,suitable to crude or product pipeline,can overcome the shortcomings of the fairly obsolete DRA. It is pointed out that the microencapsulated DRA is a better one to be developed with convenient storage/ transportation and application as well as simple post-treating process.
