High Drilling Efficiency Reverse Circulation class="lazy" src="/myres/images/load_icon.gif" data-original547 RC Rock Drill Bits For Sampling
Product Introduce:
Reverse Circulation Drilling Rigs use a dual tube rod system, which allows for a cost effective retrieval of the cuttings from the face of the borehead to the surface by transporting them through the inner tube, thus eliminating the need for sample retrieval by tripping out or by the use of a wire line core barrel system.
Reverse Circulation drilling method gives a possibility to obtain mineral samples in the early phases of a drilling project due to the high speed and low cost.
Although, Reverse Circulation drilling samples provide slightly less information regarding the formation, this shortage is largely offset by significantly reduced cost of drilling and rapid penetration rates. Sollroc's equipment offers the best choice of quality reverse circulation drilling tools to satisfy any of your drilling needs.

4. High quality well achieved
5. Lower drilling cost
6. Larger diameter hole can be drilled
Basics of Reverse Circulation Drilling:The drilling theory of air reverse circulation is similar with the theory of drawing water with air compressor.
The air flows down the annulus between inner tube and outer tube and go inside single wall pipe right at air water mixer, where produces countless tiny bubbles. These bubbles going up along the pipe and expanding simultaneously. Due to the air continuing going inside the fluid, it formed lower density mixture of air and water upper the mixer. It leads the higher density fluid in the well go up with cuttings because of the pressure difference. In this way the cuttings are brought out of the well hole very fast.

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.
