The cement basket is used for the isolation to prevent the settlement of cement slurry and drilling fluid during the cement injection construction process of the suspended sealing section.
The cement basket is installed at the bottom of the suspended sealing section.
Used to support cement in the annulus, to prevent or reduce the leakage of cement slurry, to protect the weak stratum structure.
A cement basket is a critical tool used in oil well cementing operations, specifically designed to isolate and prevent the settlement of cement slurry and drilling fluid during the cement injection process of the suspended sealing section.
It plays a key role in ensuring the proper placement of cement in the annulus between the well casing and the borehole, particularly in challenging subsurface conditions.
The cement basket is typically installed at the bottom of the suspended sealing section. Its primary function is to support the cement column and maintain it in the desired position.
By doing so, it helps prevent the undesirable migration or settling of cement slurry into weak formations or porous zones, which can lead to costly issues such as lost circulation or formation damage.
The basket acts as a physical barrier, restricting the downward flow of the slurry and protecting fragile subsurface layers.
Made from high-strength steel ribs or other durable materials, the cement basket is designed to expand and adapt to the borehole’s shape, creating a stable support platform for the cement.
This design is particularly useful in irregular wellbore sections, providing flexibility and reliability in various well conditions.
Another important function of the cement basket is to reduce or eliminate leakage of the cement slurry into weak or fractured formations.
By supporting the cement slurry, it ensures that the slurry remains in the desired zone, promoting effective sealing and isolation.
This protects the integrity of the wellbore and prevents any formation damage that could compromise the well’s long-term productivity.
In summary, cement baskets are crucial for maintaining the structural integrity of oil wells during cementing operations, providing essential support and protection for both the cement slurry and the surrounding formation.

drilling tools casing umbrella cementing basket
Cement basket introduction:
Cementing baskets protect weak formations from hydrostatic pressures exerted by the weight of cement columns. Baskets are run above weak formations on casing, tubing, and liner strings and can be used in single or multistage cement jobs.
Each basket is made of a high-strength metal and features overlapping fins to provide maximum flexibility and fluid passage while maintaining optimum support
characteristics.
Slip On Canvas Cementing Basket
The Slip on Canvas Cementing Basket comprises of slip-on type high strength with flexible bows that are mounted on the end collar.
The cementing basket has the ability to accommodate much larger than nominal hole sizes.
They are available in 4 ½” to 20” sizes and any kind of specific sizes.
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 Maintain optimum support characteristics.
The cementing basket can expand or contract as needed and can be rotated or reciprocated.
Hinged Cementing Basket
It is available in the size range 4-1/2 ” to 20”.
This device consists of flexible steel spring bows welded to Hinged collars.
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 metal fins provide flexibility and fluid passage while maintaining optimum support characteristics.
Characteristic
Simple structure, easy to handle, defend leak effectively.
The circulation is not restricted whenever in the process of running casing, during lifting and lowering or in the half way.
Not infected by the temperature and causticity liquid, can markedly reduce the cementing cost.
The cement plug should be used with relevant small casing.
