Boart Longyear wireline systems Core Barrels
Roschen Core barrel can instead of boart longyear Q series core
barrel.
Roschen Q/QTK wireline systems (represented to the left) consist of
the core barrel assembly and the overshot assembly. Both assemblies
are integral to the wireline system.
The core barrel assembly is composed of the inner-tube group and
outer-tube group. The inner-tube group is composed of: - Head
Assembly - Inner Tube - Core Lifter Case - Core Lifter - Stop Ring
The inner-tube group collects the core sample during the drilling
process and is independent of the outer-tube group. The outer-tube
group is composed of the remainder of the core barrel components: -
Locking Coupling - Adapter Coupling - Outer Tube The outer-tube
group always remains at the bottom of the hole and houses the
inner-tube group during the drilling process. Q3 wireline systems
(represented to the right) consist of the same groups as the Q and
QTK but utilize a third tube called an inner-tube liner or split
tube. The liner is placed inside the inner tube.
Applications:
1. Roschen Q systems are ideal for use in most drilling conditions
and are available for application in standard DCDMA hole sizes (A,
B, N, H, P).
2. Roschen QTK systems are optimized to allow for a larger core
sample while retaining the same hole, low fluid pressure, and
robust inner and outer tubes. QTK systems are offered in the A, B
and N sizes.
3. Roschen Q3 systems enable integral core recovery when drilling
coal, clay bearing or highly fractured formations. The liner, or
split tube, retains the core sample in its received state for
easier loading into sample trays or for storage and subsequent
presentation to the geologist. The Q3 system is only available in
surface configurations and is available in N, H and P sizes.
4. The High Productivity Coring System is a time saving surface
coring system which includes the Quick Descent head assembly,
V-Wall coring rod and the Stage3 diamond coring bit.
