Reliable performance Symmetric Casing System With Reamer-IV For Complex formation 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.
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 ConcentricTrilling will instantly ascend along the casing pipe after spurting outom the pilot bit . Hence , the negligible damage on the wall of hole canguarantee 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.
Symmetric Casing System With Reamer-IV ( Pilot bit, Reamer, Guide Device and Locking Kit )

of Pilot bit
|1.Before drilling welding the ring bit,casing shoe on the casing tube then lock the pilot bit with ring bit and casing shoe, the pilot bit shoulder will mesh with reamer.||3.After completion of drilling, the drill string with pilot bit is retrieved by s slight reverse rotation to unlock the bayonet coupling, then the ring bit stays in the hole. When the hole is finished grouting, to pull up casing and ring bits together.|
|2. Hammer’s percussive energy is transferred to the pilot bit and ring bits to crush rock. Part of impart energy push the casing forward.||4 To continue drilling with conventional drilling tools in the bedrock.|
