A full hydraulic wireline core drilling rig is a major investment for geological exploration contractors.
Before ordering, buyers should evaluate the complete drilling system rather than focusing only on the maximum depth printed in a specification sheet.
Define the real target depth and allow reasonable operating capacity for project conditions.
Confirm whether the project will use:
BQ
NQ
HQ
PQ
Other coring systems
Drilling capacity changes with rod size.
Diamond drilling applications require suitable rotational ranges for different bits, diameters and formations.
Adequate torque is necessary for stable drilling and long drill strings.
Deep holes create increasing drill-string weight.
The rig must safely handle the selected rods and downhole tools.
Evaluate feed stroke, feed control and operating smoothness.
If inclined holes are required, confirm the rig's mast adjustment and drilling-angle capability.
Efficient inner-tube retrieval is fundamental to wireline coring productivity.
Consider:
Mud pump
Drill rods
Core barrels
Diamond bits
Reaming shells
Overshots
Spare parts
International buyers should also evaluate documentation, spare-parts availability, technical communication, customization and export experience.
YKDRILL supplies hydraulic drilling equipment and supporting drilling tools for international exploration markets.
A professional purchasing decision should focus on cost per productive meter, core recovery and long-term equipment reliability, rather than simply choosing the lowest initial price.
