Casing Scraper
During drilling, fishing, completion or wireline jobs, it is critical for the downhole tools to have a obstruction-free casing so as to increase efficiency. Casing Scraper removes rust, scale, cement, mud, bullets, paraffin, perforation burrs and other obstructions or foreign material from the inside walls of casing.

Tianhe Downhole motor design d on the most advanced international design technology. We have a Closely cooperating with domestic, surgical research institutes, universities and oilfield drilling companies, and through careful research and development of R & D center in Canada, the design of technical parameters and structure can meet the most demanding oil drilling needs. Tianhe downhole motor is designed for durability and longer service life for different use conditions, with the most stringent specific tolerances for design and manufacturing standards.
The common drill pipe is a rod that connects the drill bit, delivers the drilling fluid and transmits the power in the drilling tool. Our common drill pipe conforms to SY/T5561 and API Spec5DP standards. In order to reduce the wear of the casing and drill pipe, we can weld the wear belt at the end of the drill pipe female buckle joint. Our company has obtained the production and use license of ARNCO 100XT, ARNCO 150XT, ARNCO 300XT and ARNCO 350XT authorized by the American Anke company.
The agitator can improve the effectiveness of bit weight transfer and reduce the friction between drilling tool and borehole through the longitudinal vibration produced by the hydraulic action of drilling fluid, especially in the process of directional drilling to improve the bit weight transfer and reduce torsional vibration. It is a downhole tool used to solve downhole depressurization and improve weight on bit transfer. Smooth weight on bit transfer improves the ability to adjust the bit toolface to reach further target zones. It does not require too much work to adjust the tool face during drilling, keeping the tool face stable and increasing ROP. Particularly suited for horizontal, extended-reach Wells, it can be used in conjunction with MWD, screw, and any bit.
Maintaining a clean casing is important during drilling operation, fishing or wireline tools. Likewise, packers, patches, spears, and similar tools require clean surfaces to grip. Obstructions on casing walls frequently cause these tools to fail or become difficult to operate.
Our Casing Scraper removes deposits, burrs, and irregularities from casing that might cause trouble during the operation of packers or other close tolerance equipment.
Casing Scraper has two sets of blades. Each blade is constructed using high quality cast steel for excellent scraping characteristics and long-lasting durability. These scraper blades are designed to scrape over 360º of surface area. The scraper blades are designed with a long taper for passing through casing connections with minimal chance of hanging up.
Operation
The Casing Scraper is normally connected to the work string with a drill bit attached at the bottom. Simply run the scraper into the casing or tubing using rotation or spudding to clean the inside wall of the pipe.
When ordering please specify:
