Drilling and piling tools, diamond core drilling bucket and core barrel, used in rock formations

Introduction

In engineering, there are often hard bedrocks, large flow stone layers and hard permafrost layers.
It is difficult to drill directly with a mud rotary drill bit. It is necessary to cut the ring groove with a core barrel first, and then drill a hole with a rotary drill bit.
It can greatly increase the drilling speed. The cutting teeth can be bullet teeth or cones. Core barrels with bullet teeth are used in soft formations and permafrost. Core barrels with cones are used in hard formations.

Features

1) The core barrel with elastic teeth is used to cut annular rings in rock or concrete (including reinforced concrete).

2) The core barrel with roller bit is used for very strong rock formation (compressive strength> 100Mpa).

3) The cross cutter core barrel is mainly used to break the core that is left in the borehole after the core barrel is used. It is also suitable for drilling hard jointed rocks (<100Mpa) and penetrating layers containing boulders.

Product parameters

Used in

It is suitable for large wells with low compressive strength and high drillability, mining, soft rock, such as shale, clay, salt formation and infrastructure applications.
