Cable core barrels are dual-core tubes for drilling at great depth into all formations.
The advantage compared to standard dual-core tubes is that the drill string can remain in the drill hole. The inner tube is pulled up through the pipe with a gripping device and discarded.
The core can be removed. A second inner tube set can be inserted immediately, which results in significant time savings. The borehole remains lined during extraction.
Type NSK-146/102 and NSK-176/132standard usable lengths: 1.5 m and 3.0 m.
