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.

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
