Product Details
China Wireline Core Barrel BWL3 NWL3 HWL3 PWL3 Stainless Steel
Triple Tube Core Barrel 1.5m
Stinless steel triple tube split tube
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.
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
