The Casing Scraper

Date: 26 Jan 2010
The Casing Scraper is used to clean cement,mud,embeded bullets,rust ,mill scale,paraffin,
perforation burrs and other substances from the inside walls of casing .Maintaining a clean
 casing I.D.is important to the operation of all tools used in  drilling the well. Likewise,
packers and similar tools must have a clean surface to grip.  Foreign  materials  on casing
 walls will frequently cause thesetools to become difficult to operation.
   The Casing Scraper is manufactured from a solid piece of heat treated steel. The scraper
blades fit into machined recesses and are securely held by a dovetail keeper and spacer.The
   scraper blades feature left hand helical grooves and are  hardfaced  for maximum service.
There are  sufficient  blades in the body to cmopletely  scrape the casing surface  without
rotating the tool.
   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.
