165mm MRE Overburden Symmetrical Casing Drilling System Bit for Coal Mining Equipment
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. At clockwise condition, eccentric part expanded to bring the casing tube into hole. After finished, eccentric bit closed anticlockwise and then can be lift up by the drilling machine. This type is especially suitable for diameter 114-273mm.
The Overburden Casing Drilling system is equipped with several features that optimize the drilling process and improve overall efficiency. Some of the key features of the OCD system include:
Rotating Casing System: The rotating casing system allows the drilling bit to be rotated along with the casing, enabling efficient penetration through various ground formations.
Reaming Capability: The OCD system is equipped with reaming tools that help enlarge the borehole diameter, allowing for the installation of larger casing sizes or completion equipment.
Bottom Hole Assembly (BHA): The Bottom Hole Assembly consists of various drilling tools and accessories that are attached to the casing string to optimize drilling performance and ensure borehole stability.
Cutting Removal System: A cutting removal system is used to evacuate cuttings from the borehole and maintain proper fluid circulation during drilling operations.
Monitoring and Control Systems: Monitoring and control systems are integrated into the OCD system to track drilling parameters, optimize performance, and ensure safe and efficient drilling operations.
Interchangeable Tooling: The OCD system can accommodate a variety of interchangeable tooling options, allowing for customization based on specific project requirements and ground conditions.
It is suitable for drilling water wells, geothermal wells, short mircopiles,medium mini-type grouting hole of building , dam and harbour project.
