随着石油工业的发展,原油的管道输送量日益增加,提高现有管路系统的输量,节约能源和投资,对加速石油工业的发展具有重要意义。具体措施以在原油中添加微量可溶性长链聚合物,降低原油的湍流摩擦阻力最有前途。关于油溶性高分子减阻剂的研究,各国已经做了不少工作,但许多新发明的减阻剂均为专利品,在公开发表的文 With the development of the oil industry, the pipeline transportation of crude oil is increasing day by day. It is of great significance to speed up the development of the petroleum industry by increasing the output of the existing pipeline system, saving energy and investing. Specific measures to add a trace amount of soluble long-chain polymer in crude oil, reducing crude oil turbulent friction resistance of the most promising. Many countries have done a lot of work on the research of oil-soluble polymer DRA. However, many of the newly invented DRA are patented. In the published article
