TSP (Thermally Stable Polycrystalline) reaming shell is a type of drilling tool used for enlarging the diameter of an existing borehole while maintaining its original trajectory and improving drilling efficiency. It is equipped with polycrystalline diamond cutters made from a synthetic diamond material that exhibits excellent thermal stability.
TSP reaming shells are designed to withstand high-temperature drilling conditions, making them suitable for challenging formations with high drilling temperatures. The polycrystalline diamond cutters are carefully bonded to the shell using a high-strength adhesive or brazing process, ensuring their durability and reliability during drilling operations.
The TSP cutters on the reaming shell offer high wear resistance and excellent cutting performance, allowing for efficient and smooth drilling. They can effectively handle abrasive formations, hard rocks, and other challenging drilling environments. TSP reaming shells are commonly used in applications such as oil and gas drilling, mining exploration, and geothermal drilling.
The key benefits of TSP reaming shells include improved drilling efficiency, extended tool life, reduced downtime for maintenance, and enhanced borehole quality. They provide consistent and reliable cutting performance, even in demanding drilling conditions, contributing to overall productivity and cost-effectiveness in drilling operations.
Type | B-WL(BQ) | N-WL(NQ) | H-WL(HQ) | P-WL(PQ) |
O.D. of Bit | Φ59.5mm | Φ74.6mm | Φ95.6mm | Φ122mm |
I.D. of Bit | Φ36.5mm | Φ47.6mm | Φ63.5mm | Φ85mm |
O.D. of Reaming Shell | Φ60mm | Φ75.8mm | Φ96mm | Φ122.6mm |
Note: Customized gauges of the reaming shell are acceptable, contact with our sales representative for getting more supports.
Product Advantages
* Diamond Impregnated Pad
Enables the use of large synthetic diamonds greatly enhancing wear life and eliminating the need for specialty shells in diamond exploration.
* Diamond Ground
Outer diameter grinding pre-exposes the diamond and reduces variation in size improving stability and helping to produce the longest lasting reaming shell available.
* Heavy Duty
Available with an optional heavy duty blank to prevent undercutting in extremely broken conditions (standard on oversize versions).
* Dual Pad
Available in dual pad 10” configurations for straighter holes when deviation is a concern.
Note: Q is the trademark from BLY, here we quoted for helping customers to do a selection only.
