Description

 

 

The Casing Scraper is used to clean cement, mud, embedded bullets, rust, mill scale, paraffin, perforation burrs and other substandes from the inside walls of casing, maintaining a clean casing ID is inportant to the operation of all tools uesd in drilling the well. Likewise, packers and tool similar tools must have a clean surface to grip. Foreign materials on casing walls will frequently cause these tools to become difficult to operation.
Standard connections on the Casing Scraper are API REG, Box and Pin. This allows the scraper to be installed in the drilling string 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.
