Oil Well Drilling Rig Equipment Tools API Casing Scraper
Product Introduction
Casing scraper is a new generation of wellbore cleaning tool with many new features, which maximize operational efficiency and reduce rig time. The scraper blocks are arranged on the tool to ensure 360° scraping coverage enables the scraping action to take place as pipe is run in the hole. It can be as part of a drilling or workover string, as it allows scraping to occur simultaneously with operations that require high rates of rotation.
Our Casing Scraper removes deposits, burrs, and irregularities from casing that might cause trouble during the operation of packers or other close tolerance equipment.
Advantages of Oilfield Casing Scraper:
Working principle
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.
