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.Inner tubes slide into place and seal with double o-rings as the threaded outer tubes are torqued together.

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

3.Options for additional heat treating of tool joints

4.Options for Urethane Seals to replace traditional "O" Ring setup

Working Principle:

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
