Casing Scraper

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.

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.

WG type roller reamer is used for reaming in drilling operation,especially used for the function of stabilization in drilling of the abrasive formation,it is a very popular tool, this tool can equip with three structure rollers and be suitable for hard formation in reaming operation.
Type T is machined with hardfaced sharp teeth for soft formation.
Type F is hardfaced flat teeth with anti-abrasive welding rod on its surface for medium hard formation.
Type B is with pressed-in tungsten carbide buttons, for hard formation.

1. Excavators are important and widely used equipment in construction industry. Their general purpose is to excavation but other than that they are also used for many purposes like heavy lifting, demolition, river dredging, cutting of trees etc.
2. Backhoe is another widely used equipment which is suitable for multiple purposes. This is well useful for excavating trenches below the machine level and using front bucket loading, unloading and lifting of materials can be done.
3. Dragline excavator is another heavy equipment used in construction which is generally used for larger depth excavations. For the construction of ports, for excavations under water, sediment removal in water bodies etc. can be done by dragline excavator.
4. Bulldozers are another type of soil excavating equipment which are used to remove the topsoil layer up to particular depth. These are widely used for the removal of weak soil or rock strata, lifting of soil etc.
5. Pile Driving Equipment. Another heavy equipment used in construction site is pile driving equipment in case of pile foundation construction.
6. Pile boring equipment is used to make bore holes in the construction site to install precast piles.
7. Dump trucks are used in construction sites, generally, in big construction site, off-road dump trucks are used.
8. Feller buncher is tree cutting heavy equipment used to remove large trees in the construction field.
9. Telehandlers are hoisting equipment used in construction to lift heavy materials up to required height or to provide construction platform for workers at greater heights etc.
10. Compactors or Rollers are used to compact the material or earth surface. Different types of compactors are available for different compacting purposes.
11. Paver or Asphalt paver is pavement laying equipment which is used in road construction.
12. Tower cranes are fixed cranes which are used for hoisting purposes in construction of tall structures. Heavy materials like pre-stressed concrete blocks, steel trusses, frames etc. can be easily lifted to required height using this type of equipment.
13. Wheel Tractor Scrapers are earth moving equipment used to provide flatten soil surface through scrapping.
14. Graders also called as motor graders are another type of equipment used in construction especially for the construction of roads. It is mainly used to level the soil surface.
15. Trenchers or Trenching machines are used to excavate trenches in soil. These trenches are generally used for pipeline laying, cable laying, drainage purposes etc. Both types of trenchers are available in tracked as well as wheeled vehicle forms.
16. Loaders are used in construction site to load the material onto dumpers, trucks etc. The materials may be excavated soil, demolition waste, raw materials, etc. A loader contain large sized bucket at its front with shorter moving arm.
