- 为了缓解M原油进口管道长期满负荷运行的压力，提高管道紧急工况的应对能力，进行了添加减阻剂试验，在各输油泵站添加一定量的EP系列减阻剂降低管道运行压力，增加管道输量。试验结果表明添加10 g/t减阻剂时管道输量可提高14 %左右。在试验的基础上进行了减阻剂应用，当添加10 g/t减阻剂时，在保持出站压力不变的情况下，管道输送能力提高了15 %；在保持管道输量不变的条件下，管道摩阻损失降低16 %。应用结果表明，添加减阻剂后实现了管道减阻增输的目的，提高了紧急工况的应对能力。
In order to relieve the pressure of an imported crude oil pipeline in operation at full-load and improve the response capacity of the pipeline in case of emergency working conditions, conducted is an industrial test on the pipeline, that is, a certain amount of EP drag reduction agent （DRA) is added into each oil transport pump station to reduce pipeline operation pressure and increase its transportation capacity. Test results show that injection of 10ppm DRA can increase oil transportation capacity by about 14 %. On the base of industrial test, DRA is practically applied in industry. In practical application, pipeline transportation capacity can be increased by 15 % if 10ppm DRA is injected in constant outlet pressure condition and pipeline friction loss can be decreased by 16 % with constant pipeline transportation capacity. The practical application results show that DRA injection can not only increase pipeline transportation capacity, but also reduce pipeline friction, which can reduce pipeline operation risk greatly and improve the response capacity of the pipeline in case of emergency working conditions.
