Geobor S 146mm Wireline PCD Drilling Bits
146 Geobor S Wireline Three-barrel coring barrel diamond coring bit
146 Geobor S Wireline Triple Tube Core barrel Diamond Core Drill
Bits
A heavy-duty wireline core barrel enabling 102 mm (4″) diameter
cores to be taken in a simple and cost-effective manner. It is
designed specifically for air-flush, but foam, polymer and water
flush can also be used.
This core barrel has been proven to 2500 metres in depth, with full
float capacity, or a dry hole lowering device. With a 6 mm
all-round clearance between the outer and inner tubes, full
advantage can be taken of both air and foam flush in soft
formations.
The core barrel can be used with or without plastic coreliner tubes
with the same core lifter and bit setting. The barrel accepts the
Craelius SK6L / Geobor S type core bit, or our own equivalent, with
a set O.D. of 146 mm and set I.D. of 102 mm. The barrel is rotated
with either SK6L 140 mm drill rods or by using good quality PW
casing as the drill rod.
The core barrel head is attached directly onto the inner tube and consists of three main parts: the latch assembly, which locks into the locking coupling of the outer tube, the bearing housing, and the inner tube bung. The inner tube bung incorporates a series of "Belleville" springs to allow the core to be broken easily when pulling back on the inner tube, and a float valve that allows the inner tube to be dropped into a wet hole and to control the rate of descent.
Description
Impregnated Diamond Core Bit
Impregnated Diamond Core Bit is made from high-quality synthetic
diamond and metal powder which could be used in various types of
strata. The best effect is achieved through the flexible design
according to the different strata and parameters of drilling
equipment.
Surface Set Diamond Core Bit
Surface Set Diamond Bit is produced from a single layer of natural
diamond setting on the surface of bit crown with hard matrix, and
primarily recommended for drilling relatively soft, abrasive,
unconsolidated formations that are not effectively drilled by
impregnated diamond bit. It is also recommended for drilling harder
formations, which the available rotary speeds and bit loads are
insufficient to use impregnated diamond bits due to drilling
equipment limitations.
In most cases, Surface Set Diamond Bits will provide higher rates
of penetration than in softer formations due to the greater degree
of exposure of the individual diamond crystals.
Tungsten Carbide Core Bit
Tungsten Carbide Core Bits are designed especially for soil
investigation and geotechnical drilling, but also suitable in some
applications for mineral exploration. As the tungsten Carbide is
softer than diamond stones, the formations are limited in the range
of soft or some medium rocks, like the overburden drilling,
cleaning of drill holes, e.g. for the removal of steel fragments in
hole.
PDC Core Bit
PDC Core Bit has a long working Life, very fast penetration and high percentage core recovery in soft to hard rock formations. PDC bit mostly be used for drilling with air, mud or foam flushing.
