Downhole Well Bore Clean Tools Casing Scrapers Rotating Scraper
Casing Scraper is a kind of well bore clean tools, which is used to
remove dirt which may be left over the inside walls of casing, such as cement, mud, embedded bullets, rust, mill scale,
paraffin, perforation burrs and other substances. So as to make all down hole tools pass through unblocked. Especially
when a small circular clearance is available between the down hole
tools and casing inside diameter, the complete scrapping becomes
more necessary before further working. Now in the large petroleum
well scrapping in the internal wall of casing by use of casing
scraper is a necessary step.
Features of casing scraper
* Full circle blades contact 600o surface at once.
* The casing scraper is design with short and compact structure
* It is easy to assemble and disassemble the casing scraper.
* There is longer guide taper on blades for passing through joints without hanging.
