Description
Rotating Casing Scraper
The Rotating Casing Scraper is designed to clean up cement sheath, perforation damage, debris, left behind on the ID of the casing. It is designed to be run with a motor, right above the bit. With its Spring Loaded Design, full casing contact is mainta ined with the Carbide Inserted B lades throughout the milling job.
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.
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.
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 360 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.
