NQ BQ HQ core barrels are used for wireline core drilling
Q series Core Barresls
Wireline drilling is the special method of removing the core.
When the driller wants to remove core from a conventional core drill, the entire core barrel has to be removed from the hole. This is time-consuming, as each rod has to be removed one at a time.
With wireline drilling, a barrel of core can be removed from the bottom of the hole without removing the rod string. When the driller wants to remove the core, an overshot is lowered on the end of a wireline. The overshot attaches to the back of the core barrel inner tube and the wireline is pulled back and the inner tube disengages itself from the barrel.
Generally Q series Core Barrels are used when high quality core is required in broken, fractured formations.
1.5m and 3.0m length core barrels are avaiable.
Q series Core Barresls available: AQ, BQ, NQ, HQ, PQ, NQ3, HQ3
