Wireline Triple Tube Core Barrels
GBS Large Diameter Geotechnical Wireline Core Barrel
Wireline Double Tube Core Barrels
Wireline core barrels are used when coring to greater depths, mainly because they eliminate the need to couple and uncouple the rod string each time the core is retrieved. An overshot device is dropped on a cable and directly couples onto the inner tube assembly, allowing fast retrieval of the core after each core run.
The double tube wireline core barrel is converted to triple tube by incorporating a split steel tube inside the inner tube. In addition, a piston and pump-out adaptor is provided for pumping out the split steel tube when it is full of rock core. The stop ring, core lifter case and core lifter also differ from the standard double tube core barrel, being slightly smaller in diameter in order to accept and retain the slightly smaller core.
An alternative method of converting the double tube to triple tube is by incorporating a clear, semi-rigid PVC coreliner inside the inner tube instead of the split steel tube.
Available in DCDMA sizes B, N, H. and P.
Advantages:
1. Faster coring at greater depths
2. Good stability due to constant diameter of the drill string
3. Excellent hydraulics
4. Good core recovery even in highly broken formations.
