Introduction
SUPER Unique Sharp-Razor Series is a heavy duty wellbore clean-up scraper suitable for all downhole conditions and with robust, high performance features.
Run separately or as part of a comprehensive wellbore clean-up, the SUPER Unique Sharp-Razorâ?¢ is designed to effectively remove cement and other debris from the casing wall, through reciprocation.
The scraper cage flexes like a spring, to conform to the casing internal surface, to mechanically remove hard debris from the casing.
The alloy bronze bearings feature both axial and radial elements to allow extended rotation in harsh environments preventing tool and casing wear. The Heavy Duty version includes an integral string mill. The Standard Duty version comes with a plain external diameter.
Junk Trapper and catch
One Salvage cup usually pick up on the drill bit or milling tool, with its collection of cups will circulate in borehole couldn't recovered heavier small falling objects.It can also be used for casing scraper above, make the casing scraper operation is fast and clean.
TwoSalvage cup salvage fragments falling object is mainly used in drilling process, such as cemented carbide teeth, bit bearing, etc.It is to keep the bottom clean, improve the service life of drill bit, drill bit to reduce and prevent accidental damage plays an important role.
Structure
Salvage cup is mainly composed of spindle, wiper block, outer tube, the joint and so on, as shown.Because the manufacturer is different, although its structure is similar, but not exactly the same, can be selected according to downhole conditions.
Before completion string into the well, to be on the inside casing packers, and other hydraulic anchor packer position scraper operations. Flow area of conventional scraper with the annular space can not meet the requirements for mud wells, requiring scraping the wall from a string and then carried down into the well string pass through wells, wash well and for the pulp operations, which led to repeated tripping drilling, completion efficiency low. In this regard, I developed a hydraulic scraper flushing integration tools.
Tools into the well, scraping the wall, close scraper, wash well, for the pulp and other tools in accordance with design is completed, the column will be completed trip scraper, wash well, for the pulp operations.
Using this tool, originally scraper and wash wells drilled from under twice the combined operations, not to mention the string after scraping the wall can be carried out through the flushing and for pulp operations, improve efficiency and a successful completion rate.
How it works: In the bottom of the wall is connected to the wiper switch sleeve, scraping the wall at the end of the required diameter, for pulp, wash well and other operations, from the wellhead to the pitching sleeve tee switch by pressing after scraping the inner column on the wall is moved towards the two outer cylinder extending scraper blade pressed back cavity. Continue pressing the switch on the sleeve loop holes open, due to the recovery after the blade so that the area of the annulus between the casing scraping the wall with the increases, improved for pulp, flushing efficiency, so that the original need for tripping twice tube job column can be completed once go down operations, reduce tripping times and reduce operating costs.
It is meanly used in fish trouble stuck by debris,such as directional well drilling tools,drill pipe,tubing and perforating guns etc.Also,it can be used milling packers,in order to release packer by milling as little as possible.
Featuresï¼?
Compact design- Single piece mandrel.
High strength rare earth magnets.
Fixed stabilizer sleeve to provide stand off when POOH.
Optional dedicated flow channel to prevent flow path restrictions when packed full of
debris
Advantagesï¼?
Removable magnets for body inspection .
Recovered material is easily removed on location.
High temperature rating on magnets up to 350%F (177°C) .
Debris channels allow for larger volume of ferrous material to accumulate.
Five blades mill is used for milling bridge plugs, slip inserts, and other smaller objects that are
dropped or lost in the well. Nozzle size and position are optimized by fluid dynamics analysis, so
that the cutting structure is always milling virgin formation. Five blades mill is used for milling
composite plugs, cementing plugs.
Features
Fluid dynamics analysis for optimizing flow for deb
The company has introduced the original imported carbide cutting teeth, which can be used for various types of downhole cutting and milling operations. We are able to provide all sizes and shapes of clastic milling, all sizes of milling shoes and different diameters of milling cone or drill string milling. This type of shoe is ideal for metal debris that have fallen into the well, such as bit cone, tong dies, packers, and sleeve milling stuck or cementing pipes.

Introduction
Grand-Mix (GM) consists of the latest generation scraper, brush and high capacity magnet, combined them into a simplified and rugged tool, which has an integral magnet section to capture ferrous debris, scrapers to dislodge difficult to-remove debris, and brushes to disturb the sheath and any other fluid build-up on the inner wall of the casing or liner. The tool can be run in the inner production riser, casing, and liner to remove a combination of scale, rust, mud film, drilling debris, ferrous debris, and pipe dope.
Features
One tool carries scrapers, brushes, or magnets on the same mandrel.
Large flow area between magnets to capture large debris.
Brush component can be readily redressed at remote locations.
Available with any tubing connection to run directly on the completion tubing.
Application
the Grand-Mix can be configured for any Casing and Tubing combination with matching metallurgy and connections
We introduced Opti-Cut cutting teeth from Backer Hughes,and each cutter had the optimal geometry, so that no matter how the cutting teeth are arranged on the cutting or milling tools, the blade edge or tip is facing up. When the teeth wear out, new blades and tips will appear. The new cutting teeth have a total of 16 blade tips and 8 blade edges. Applications range from tubing fishing, packer milling, sleeve milling, casing/pipe cutting, and milling to wherever extremely sharp cutting edges are required.
