High Speed Core Drilling Equipment , Wireline Drilling Tool Rods Easy Loading
We offers a complete line of single & double and triple tube core barrels, which will provide superior performance and obtain the full recovery of the sample in any application of diamond core drilling.
The series can be divided into BQ, NQ, NQ3, HQ, HQ3, PQ and PQ3 types, is very commonly used for mineral exploration for deep holes because of practical usage.
Wireline core barrels eliminate the major time consuming operation of using standard double tube core barrels – pulling, stacking and lowering drill rods each time the core barrel is full.
Wireline tube Core Barrels enable integral core recovery when drilling coal, clay bearing or highly fractured formations. The split tube retains the core sample in its received state for easier loading into sample trays or for storage and subsequent presentation to the geological.
A Overshot is available for each size of core barrel, lower on the wireline to recover the inner tube assembly containing core.
