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.

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.
