Abstract

Способ удаления из трубопроводов отложений, таких как гидратные пробки, включающий следующие этапы: введение в трубопровод проталкивающей болванки, соединенной с возвратной линией; продвижение болванки вперед в трубопроводе посредством нагнетания жидкости в кольцевой зазор между трубопроводом и возвратной линией, при этом удаляемые отложения непрерывно или периодически пступают в возвратный поток, направляемый из области перед болванкой через возвратную линию;отсоединение возвратной линии от болванки после удаления достаточного количества отложений, установка возвратной линии на прежнее место, и продвижение болванки дальше по трубопроводу посредством нагнетания жидкости в место расположения болванки по мере возврата жидкости.
