Advantages of Concentric Drilling

1.Drilling Straight and fast

,Theoretically, concentric drilling makes sure the hole in all formations such as gravel bed, sand bed and pebble bed etc.is considerably straight the drilling speed fast and the drilling torque relatively small.

2.The torque for Concentric drilling is much less than for eccentric drilling. 

A smooth and steady drilling may be achieved using ring bit on all conditions and create big hole even if a small drilling rig is used.

3.Easily Unlocking-relocking

Unlocking the system is sometimes required during process. relocking is easy since there are no eccentric components that must be opened or closed inside the hole.

4.Drilling in any angle.

Concentric drilling system can drill the hole at any angle.

5.Effective cuttings discharge.

The airflow for cutting discharge purpose during the Concentric drilling will instantly ascend along the casing pipe after spurting out from the pilot bit. Hence, the negligible damage on the wall of hole can

guarantee effective cutting discharge.

6.Easy-to-operate and system security

Drilling workers are relieved of the need to maintain their continuous and constant attention on drilling process since Concentric drilling can carry on smoothly.

7.Economical and cost-effective.

The structure and principle of operation of Concentric drilling system can guarantee considerable reduction in downtime, fewer consumable and lower operation costs.
