Product Introduce:

Reverse Circulation drilling, or RC drilling, is a method of drilling which uses dual wall drill rods that consist of an outer drill rod with an inner tube. These hollow inner tubes allow the drill cuttings to be transported back to the surface in a continuous, steady flow.Reverse circulation. The course of drilling fluid downward through the annulus and upward through the drill stem, in contrast to normal circulation in which the course is downward through the drill stem and upward through the annulus. Seldom used in open hole, but frequently used in workover operations.

 

Adavantages:

      A higher percentage of uncontaminated cuttings

      Drilling rate similar to open hole drilling, but can often be faster and penetrate greater depths

      One of the most accurate drilling methods

Quick retrieval of sample rates

Dry samples allow for easier analysis

 

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.
