Product Introduce:

Reverse Circulation (RC) drilling is one of the three main types of mineral exploration techniques. Used to compile sample rock cuttings, the drilling process relies on hollow inner tubes to transport samples back to the surface in a continuous flow, using compressed air.

Reverse circulation (RC) drill pipe is a dual wall pipe used for uncontaminated, representative and continuous samples. It is also used to reduce air requirements and maintain up hole velocity in larger diameter drilling applications. RC Inlet air passes between the inner tube and outer barrel. Cuttings are evacuated through the center tube.

Adavantages:

1.Reliable and uncontaminated samples

2.High drilling penetration rates

3.Versatile in tough conditions

4.Less handling results in cost reduction and faster turnaround times

5.Abrasion-resistant alloy steel inner and outer tubes extend life of the drill pipe

 
Working Principle:

Reverse circulation is achieved by blowing air down the annulus of the rod, the differential pressure creating air lift of the water and cuttings up the inner tube which is inside each rod. It reaches the deflector box at the top of the drill string then moves through a sample hose which is attached to the top of the cyclone.

The drill cuttings travel around the inside of the cyclone until they fall through an opening at the bottom and are collected in a sample bag. For any drill hole there will be a large number of sample bags, each one marked to record the location and drilling depth that the sample was obtained.

The collected series of sample bag cuttings are later taken for analysis to determine the mineral composition of the drill hole. The analysis results of each individual bag represents the mineral composition at a particular sample point in the drill hole. Geologists can then survey the drilled ground analysis and make decisions about the value of the overall mineral deposit.

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:
