Description
Cement umbrella like an inverted handleless umbrella, which consists of canvas and a few pieces of spring composed of canvas made of funnel-shaped fixed in the spring, the cement umbrella is also made of steel sheet overlap.
Cement umbrella is an annex to cementing construction and is usually suitable for use in the backlash cement process and graded cementing to control the position of the cement section. Used to support the cement in the air, to prevent or reduce the loss of cement slurry, the type suitable for use within the casing and the use of naked eye, encountered irregular sections and shrink diameter section, you can freely stretch.
Features
- Non-welded, pressed by punching, high strength.
- Compared with single bow centralizer, the restoring force is higher while the starting force and running force are lower.Therefore, it can be run in vertical, highly-deviated and horizontal wells.
- Hinged design allows convenient field installation.
- Can be unfolded and stacked flatly, saving storage and transportation cost.
Slip On Canvas Cementing Basket

With this type of design cementing basket can be rotated and reciprocated.
Bows are hardened and tempered for maximum strength and uniformity.
It is run on casing or liners above weak or porous formations to provide protection
from hydrostatic pressure generated by the cement column.
Its overlapping canvas/metal fins provide flexibility and fluid passages which maintaining optimum support characteristics.
The cementing basket can expand or contract as needed and can be rotated or reciprocated.
Hinged Cementing Basket
