Abstract
Снижающая сопротивление течению композиция, включающая частицы по меньшей мере двух различных снижающих сопротивление течению полимеров. Различные снижающие сопротивление течению полимеры можно получать разными способами, такими как полимеризация в массе или эмульсионная полимеризация, а частицы таких различных снижающих сопротивление течению полимеров могут обладать разными средними размерами. Снижающие сопротивление течению композиции можно добавлять к углеводородсодержащей жидкости для снижения падения давления, обусловленного турбулентностью потока углеводородсодержащей жидкости по трубопроводу.
