Product Description

190mm MRE Overburden Concentric Casing Drilling System Bit for Rock Formation

Product Description

MRE Concentric under reaming drilling system is designed for unstable ground conditions. In the process of drilling, it could carry down the casing pipe to the hole to protect wall to achieve drilling work. This type is especially suitable for diameter 114-273mm.

The Overburden Casing Drilling system consists of several key components that work together to facilitate efficient drilling in challenging ground conditions. The primary components of an OCD system include:

1. Casing: The casing serves as both a drill string and a support structure during the drilling process. It is typically equipped with a drilling bit at the bottom end to penetrate the subsurface layers.

2. Drilling Rig: The drilling rig provides the necessary power and mechanical support to drive the casing into the ground and rotate the drilling bit.

3. Drilling Tools: Various drilling tools such as reamers, core barrels, and stabilizers are used in conjunction with the casing to optimize the drilling process.

4. Fluid Circulation System: A fluid circulation system is employed to cool the drilling bit, remove cuttings from the borehole, and stabilize the surrounding formation.
