The non-rotating casing scraper is one of the indispensable auxiliary tools for well completion, testing and downhole operations. Its main purpose is to remove cement, sand, scratches, paraffin, burrs and other attachments on the inner wall of the downhole casing, protect the cleanness of the inner wall of the casing, and facilitate the normal operation of all drilling tools.
Each set of products is composed of four rows of cutter plates, which can realize 360 degree all-round non-dead angle scraping. The cutter plate does not rotate with the drill string, and only moves up and down relative to the inner wall of the casing, without rotating movement, so the casing will not be damaged.
