T2 core barrel

tubo testigo T
Are recommended when looking for a good recovery on compact formations, which is fine gravel drilling.
The annular space between the outer and the inner tube is narrow, so it will work with clean water or with very low viscosity mud.

Circulation fluid enters in the head through the rod and passes through
holes into the annular space between tubes, down to the cutting tool,
cooling it and helping the removal of the cutting, which will ascend with
the fluid through the annular space between the outer tube and the walls
of the hole to the surface, so that fluid only come into contact with the core
in the cutting area. The inner tube is fixed to receive the core, while the
outer tube transmits the rotation from the rod to the bit, through a bearing
housing installed in the core barrel tube head.
