reverse circulation drilling

Product Introduce:

 

 

Reverse circulation (RC) drilling uses a bit attached to a down-hole hammer to produce a hole. Unlike diamond drilling, RC drilling produces samples of rock cuttings rather than a sample of rock core. The down-hole hammer is powered by compressed air, which also acts as the medium bringing the drill cuttings up to surface.

 

Adavantages:

Reduces air loss into the formation
Has less impact in sensitive areas
Energy efficient

 

Woring Principle:

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.

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.
