API standard oilfield drilling use casing scraper

Casing Scraper

Casing scraper is used to removal of the dirties which may be left over inside wall of casing, such as cement scale, sandy soil, embedded bullets, score mark, hard wax, various salt crystals or deposits, perforation burrs and iron oxide resulted from rusting, so as to keep the wall of casing clean and to lay down all down hole tools freely. Likewise, packers and other similar tools must have a clean junction surface.

The Casing Scraper is manufactured from a solid piece of heat treated steel. The scraper blades are fit into machined recesses and are securely held by a dovetail keeper and spacer. The scraper blades feature left hand helical grooves and are hard faced for maximum service. There are sufficient blades in the body to completely scrape the inside wall of casing even without rotating the tool.

Standard connections on the Casing Scraper are API Reg., Box and Pin, which allows the scraper to be installed between the bit and the bit sub. The bit is run below the scraper to serve as a guide and prevent plugging the circulation hole through the scraper.
