Product Introduce:

In reverse circulation, drilling fluid (usually water or very thin mud) flows down the annulus, up the drill pipe to the suction side of a pump, and into the tank or pit. Cuttings are lifted inside the drill pipe that has a smaller cross section than the annulus. Suction lift of the pumps limits this method to approximately 450 ft depth at sea level. The method that is preferred for geothermal wells utilizes an air pipe inside the drill pipe to provide the lift, and a cyclone or similar separator to separate air from the water and cuttings mixture. The air lift greatly increases depth capacity.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:

Faster and more efficient, reducing costs and providing greater returns. RC drilling achieves higher production rates and can achieve up to 200/300 metres per day. This means that results can be delivered to clients faster, as the drilling itself takes less time. The speed and efficiency involved also reduces manhours on the drill rig, meaning savings on overall staff hours. Thanks to the power and efficiency of the equipment, RC drilling is more resilient in harsh environments, which makes it a cheaper option overall. In fact, RC drilling has been shown to reduce costs by 25-40%.

 

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.
