Concentric Overburden Driling System (High Air
Pressure)
Feature:
On the basis of Eccentric Overburden Casing
Systems, our factory created the Concentric Overburden Driling
System, also called as the Five Sets, which has won design research
and development patent.
Working
Principles:
A. When drilling, the reamer swings out and
drills a hole larger than the externa diameter of the casing
tube.
B. When the required depth has been reached, the drill is reversed
and the reamer swings in to its minimum diameter, allowing the bit
to be lifted up through the casing, which is left in the hole.
C. Drilling can continue with an ordinary DTH drill
bit.
THREE
reamer wings advantages:
1. multi-orientation simultaneously crush, so as
to bear stress evenly and subsequently impact resistance.
2. dislaging easily
3. Drilling rod and casing could accelerate following
up.
4. Operation, assemble and unassembled the
equipment is easy.
5. Multi-axis suspension is adopted, to avoid reamer from falling
of.
