Drilling Machine 2000mm kelly box drilling core barrel with roller bits Rotary Drilling Rig
The single-cone bit is a kind of deceleration bit, that is, the rotation speed of the cone is smaller than the rotation speed of the drill bit. It is mainly used to chamfer the broken rock, and is suitable for the old well window sidetracking and deepening of the old well under high speed and high drilling pressure. Wait for small well bore drilling operations.
Advantage
1. The working torque is lower than that of the PDC bit under the same drilling pressure and formation conditions, which can reduce the expansion of small-sized drilling tools and avoid down hole accidents.
2. The advantages of the single-cone bit with the tricone bit and the PDC bit are different. They are more suitable for the plastic formation than the tricone bit, and can also be applied to the PDC bit. Hard inter layers and other complex formations.
3. With the underground power drill can achieve high speed and special drilling needs.
Feature
1. Cutting ring with rock drilling bits and releases the internal stress of rock；
2. Drilling with the method of rolling and squeezing can increases the anti-wear ability of the barrel;
3. Applicable layers: backfill layer, medium weathered rock, bedrock;
Customizable Items
