Core barrel with single cone for piling and drilling
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. Suitable for large-size casing well sections, mines and
infrastructure drilling.
2. The core barrel with roller bit is used for very strong rock
formation (compressive strength>100Mpa).
3. The core barrel with roller bit adopts high carbon steel and
special bit angle to maintain the strength and efficiency of
drilling.
