WIRELINE N CORE BARREL

WireLine N Core Barrel (WL N 10.00.00.000) 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 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.
