Casing Scraper is ideal for the removal of mud, cement, bullets,
rust, scale, paraffin, perforation burrs and other obstructions
from the inside walls of casing. Maintaining a clean casing I.D. is
important when operating drilling, fishing, or wireline tools.
- Full circle blades contact 600° surface at once.
- Short, compact, easy to assemble and disassemble.
- Longer guide taper on blades for passing through joints without
- Vertical and rotary operation may be run on wireline or drill pipe.
- Investment cast tool steel blades allows maximum scraping ability.
Casing Scraper is ideal for the removal of dirt which may be left
over the inside walls of casing, such as solid cement, hard wax,
various salt crystals or deposits, perforation burrs, iron oxide
residues resulted from rusting, so as to make all down hole tools
pass through unblocked. Especially when a small circular clearance
is available between the down hole tools and casing inside
diameter, the complete scrapping becomes more necessary before
further working. At present in the large petroleum well scrapping
in the internal wall of casing by use of casing scraper is a
Before run into downhole, the max. installation size of blade shall
be bigger the inside diameter, after run into downhole, the blade
is pressed to press the spring down, theradial force is given by
spring. When hard materials need to be scrapped, scrapping for
several times must be done before scrapped to casing inside
diameter. The casing scraper is connected on the low end of drill
string, the moving of drill string up and down make an axially
feeding in the scrapping operation. It is showed in the structure
that each spiral blade has two internal and external curved
scrapping edges. When the blade is working for reciprocating
scrapping, the internal edge and external edge are working in
turn,and there is a wider transverse edge band between two
scrapping edges stands a cutting and milling action to the cut
surface. The strap blades are uniform distributed on the scraper so
that the returned mud can take the scraped substances away.
