Hole Dia 76mm Core Dia 47.6mm Wireline N Core Barrel Assembly 1800m

HOLE DIA 76MM CORE DIA 47.6MM WIRELINE N CORE BARREL ASSEMBLY 1800M

WireLine N Core Barrel is used in core drilling of boreholes with wireline inner core barrel (WireLine Coring System): drilling of Ø76 mm diameter boreholes up to 1800 m deep in solid, semifractured and fractured rocks of VI-XII drillability category. WireLine core barrel is designed for receiving and preserving of core while drilling and also for separating and lifting of core from the borehole bottom to the surface without lifting of drill string.

Wireline drill tools can lift drill core from drill rods without picking up bits. All the tools include principal parts of the drill tools, overshotassembly, drill rods, holding dog, circle wrench and etc. Their advantages are higher penetration, higher core recovery ratio, longer bit life and lower our ab intensity; and the advantages get more clear with the increasing of hole depth.

WireLine Core Barrel consists of:

• core barrel;
• locking and adapter couplings;
• outer tube;
• landing ring;
• stabilizer.

Inner barrel consists of:

• N head assembly 
• core lifter;
• inner tube.

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

Wireline double core barrel consists of:

1. Head Assembly

2. Inner Tube: 1.5m or 3.0m

3. Stop Ring

4. Core Lifter
