Wire-line core drilling tools can lift core from drill rods without
picking up coring system. A complete set of wire-line drill tools
include: Core barrel assembly, overshot assembly, drill rods, holding
dog, hoisting plug, circle wrench etc. It has some advantages such as
high penetration rate, high penetration rate, high core recovery ratio,
long bit life and lower labour intensity. The advantages can get more
clear with the increasing of drill hole depth.
We can supply B, N(3), H(3), P(3), N2, N2U, BU, NU, HU, LTK60 corebarrel.
Brief Introductions of Core Barrels
Our
core barrels include wireline (Q series), T2-101, LTK60 core barrels.
We also provide core barrel parts such as core lifters, core lifter
cases and locking couplings. This kind of core drill strictly complies
with the international standards. Core drilling tools can lift core from
drill rods. During this process, picking up coring system is not
necessary. Core barrel assembly, overshot assembly, drill rods, holding
dog, hoisting plug, circle wrench are all belong to drill tools.
Features of Core Barrels
1) High penetration rate and high drilling efficiency.
2) High core recovery rate.
3) Long bit life and lower labor intensity.
4) Adopt abrasion resistant material.
