Reaming Shell

Reaming shell is an important part to connect the drill bit with the core barrel, which is set with natural or synthetic diamond.
Reaming shell is used to clean and maintain the correct constant diameter of the hole, thus to ensure the adequate clearance for the core barrel and the replacing drill bit. Diamond reaming shell can also acts as a stabilizer. Our company manufacture various types of reaming shell to meet the needs of different working condition.

The diamond reaming shell plays a crucial role in mining exploration and mineral coring activities. Here are the main purposes of using a diamond reaming shell in these applications:

1. Borehole Enlargement: One of the primary purposes of a diamond reaming shell is to enlarge the diameter of a pre-existing borehole. In mining exploration and mineral coring, it is often necessary to drill through various formations to access the target mineral or ore body. The diamond reaming shell allows for controlled and precise enlargement of the borehole diameter to accommodate larger-sized drilling tools or casing pipes.

2. Smooth Borehole Walls: Diamond reaming shells contribute to smoothing and polishing the borehole walls. As the diamonds on the shell interact with the formation, they help remove any rough or irregular surfaces, ensuring a smoother and more uniform borehole. This is particularly important in mineral coring, where a high-quality core sample is desired.

3. Debris Removal: During the drilling process, the diamond reaming shell assists in the removal of cuttings and debris from the borehole. The cutting action of the diamonds grinds and shears the formation, generating rock chips and fragments. The drilling fluid or mud circulated through the drill string carries away these cuttings, preventing them from obstructing the drilling process or interfering with core recovery in mineral coring.

4. Core Barrel Alignment: In mineral coring, the diamond reaming shell has an additional purpose of aligning the core barrel. The reaming shell is often used in conjunction with a core barrel, which houses the core sample. By placing the reaming shell above the core barrel, it helps guide and stabilize the core barrel during the drilling process, ensuring accurate and centered core recovery.

5. Drilling Efficiency and Productivity: The use of a diamond reaming shell in mining exploration and mineral coring can significantly enhance drilling efficiency and productivity. By enabling the enlargement of the borehole diameter, it allows for the deployment of larger-sized drilling tools, such as core barrels or casing pipes. This facilitates faster drilling progress, reduces the risk of getting stuck in the hole, and improves overall drilling performance.

6. Preservation of Core Integrity: In mineral coring, the diamond reaming shell plays a role in protecting the integrity of the core sample. By smoothing and polishing the borehole walls, it helps minimize damage to the core during retrieval. Additionally, the removal of debris and cuttings by the reaming shell reduces the likelihood of contamination or loss of the core sample.

Overall, the diamond reaming shell is a critical tool in mining exploration and mineral coring, enabling efficient borehole enlargement, smooth borehole walls, debris removal, core barrel alignment, and preservation of core integrity. Its use enhances drilling operations, improves productivity, and contributes to the successful extraction of valuable mineral resources.
