RC Dual Wall Drill Rods 4 1/2'' Metzke Thread 3m For Drilling
Project
Product Introduce:
SOLLROC reverse circulation heavy duty drill pipes outclass similar
products on the market in both value and quality. SOLLROC's RC
drill rods also provide the driller with excellent durability,
thanks to the highest quality products which were used during the
manufacturing process. they last longer and drill deeper with the
same air, offering the most value for the price.
Drilling of wells is carried out with hydro-transport of the core
delivered on the surface along the internal channel of the double
drill string.
Adavantages:
1.Reliable and uncontaminated samples:
When the cutting travels through the bit into the inner tube
towards the cyclone, it is not introduced to other areas of the
hole, keeping it free of cross-contamination. This creates the
possibility of producing large quantities of high quality, reliable
samples.
2.Sample cuttings are easier to catalogue and keep track of.
Because the samples collected will have an exact location and depth
at which they were found, surveyors and interested parties will be
able to locate mineral deposits more precisely.
3.High drilling penetration rates:
RC penetration rates are comparable to open drilling methods and
are often faster at greater depths. Sample velocity through the
inner tube can reach speeds of 250 m/sec, making the retrieval of
drill cuttings a rapid but safe method requiring fewer man-hours.
4.Versatile in tough conditions:
RC drilling is fairly straightforward and requires far less water
than diamond drilling, making it ideal in places such as Australia,
where water may be scarce or costly. RC drilling is also a more
cost-effective method than diamond drilling, with operating costs
reduced by up to 40% compared to diamond drilling.

Working Principle:
High pressure air transported into somewhere of the well along with
air pip, via mixer to inject the high-pressure air into the pipe
with liquid, due to the density of mixed liquor lower than flushing
liquor therefore a differential pressure occurred between pipe and
sample tube that to make the mixed air and liquid flow up fleetly
by the fluid column pressure and take the rock debris into powder
out to the ground from bottom of the hole continuously. By this
drilling method will provide with advantages like high penetration
rate, quality pore-forming and fewer hole collapse rig drilling in
loose formation.
This series reverse circulation pipes can increase penetration in
lost-circulation formation, reduce drilling fluid consumption,
protect reservoir stratum and save the cost of other consumption
tools. In additional, the pipes can be worked in two direction
circulation drilling ways to control the well drilling. By reverse
circulation method to kill the well the heavy mud can be
transferred directly to the bottom of the well, no periodic
circulation and save time.

About us:
SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’,
is a technique of drilling that uses dual wall drill rods that
consist of an outer drill rod with an inner tube. By using
compressed air to extract rock fragments sample,the samples travel
through rods to a sample splitter at surface, avoiding all contact
between the samples and the borehole wall that allows samples to be
retrieved with minimal contamination,which is mainly used in deep
hole exploration and mining grade control.
Delivery Way:
By Air, By express or By Sea
