The invention relates to a pipeline internal scouring mechanism which is used for cleaning the inside of a pipeline, in particular to the internal cleaning of a downhole tubular column.
Background
The inner wall of the downhole tubing can be scaled, waxed and accompanied by corrosion problems after long-term operation. After the underground pipe column is taken out, the inner surface and the outer surface of the underground pipe column need to be cleaned, and then detection and testing are carried out. Because the length-diameter ratio of the underground pipe column is larger, the inner hole of the pipeline is smaller, and the conventional manual cleaning is more complicated. At present, a downhole tubular column, particularly an underground oil pipe is taken out, and a steel wire ball and foam ball cleaning mode is mainly adopted. The steel wire ball and the foam ball are plugged into the pipeline in a conventional cleaning mode, and are pushed to pass through the inner cavity of the pipeline by water containing a cleaning agent, so that the cleaning effect can be achieved by repeated operation; or the thin rod is stretched into the pipeline and dragged back and forth to clean and scrape the inner wall of the pipeline, but the pipeline is long, so that the construction is very inconvenient.
