Geological drilling tools are essential equipment in mining exploration, mineral resource evaluation, and water well drilling projects.
The performance of drilling tools directly affects drilling efficiency, penetration rate, core recovery, and overall drilling cost.
In modern core drilling operations, Q series drilling tools are widely used, including BQ, NQ, HQ, and PQ systems.
These standardized systems define core diameter, hole size, and matching drilling tools such as diamond core bits, drill rods, core barrels, and reaming shells.
They are suitable for different drilling depths and geological formations.
Diamond core bits are the most critical cutting tools in geological drilling.
According to application, they are mainly divided into impregnated diamond core bits and surface-set diamond core bits.
Impregnated diamond core bits are widely used in hard rock formations such as granite, basalt, quartzite, and magnetite.
The diamond particles are evenly distributed in a metal matrix.
During drilling, the matrix wears gradually, exposing new sharp diamonds continuously.
This ensures stable cutting performance, high wear resistance, and long service life.
Surface-set diamond core bits are more suitable for softer or less abrasive formations.
They provide faster penetration rates but have a shorter service life compared to impregnated bits.
Drill rods are key components for transmitting torque and drilling pressure from the drilling rig to the bit.
High-quality drill rods must have high tensile strength, good straightness, and precise thread connections.
Stable threads reduce vibration, minimize energy loss, and prevent thread damage during deep drilling.
For deep drilling and mineral exploration, the combination of high-performance diamond core bits and durable drill rods significantly improves drilling efficiency and reduces downtime.
Core barrels are used together with core bits to collect rock samples.
High-quality core barrels help improve core recovery rate and maintain sample integrity, which is critical for geological analysis.
Reaming shells are auxiliary tools used to maintain hole diameter and stabilize the drilling system.
They help reduce vibration and improve drilling stability in complex formations.
In water well drilling projects, drilling tools must perform reliably under long working hours and varying geological conditions.
Stable drilling tools can improve penetration rate, reduce tool consumption, and increase overall efficiency.
