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, aseemble and unassembled the equipment is easy.
5. Multi-axis suspension is adopted, to avoid reamer from falling of.
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.
