DHD3.5 Shank Overburden Eccentric Casing Drilling System for Water Well Construction
Eccentric bit is made up of a pair of chain emmbedded to guide apparatus, and ensure the bit is not contacting and damaging the retaining ring when it is rotating. When rotated clockwise, eccentric part will be expanded to bring the casing tube into hole. After completing, eccentric bit will be closed while rotated anticlockwise, and it can be lifted up by the drilling machine. This casing drilling bit is especially suitable for diameter 114-273mm.
Features of Overburden Casing Drilling System:
The Overburden Casing Drilling system features a unique design that combines casing advancement and drilling into a single, efficient operation. Key components of this system include:
Casing With Built-in Drill Bit: The casing used in the OCD system comes equipped with a drill bit, allowing for simultaneous drilling and casing advancement. This eliminates the need for separate drilling and casing operations, saving time and resources.
Reaming Shells: Reaming shells are utilized to enlarge the borehole diameter as the casing is advanced through challenging formations. This feature helps to maintain borehole stability and ensures smooth casing installation.
Drilling Fluid Circulation System: The OCD system incorporates a drilling fluid circulation system that serves to cool the drill bit, carry cuttings to the surface, and provide stability to the borehole walls. This system plays a crucial role in optimizing drilling performance.
Casing Shoes: Specialized casing shoes are attached to the bottom of the casing to facilitate drilling through various formations. These shoes are designed to withstand the rigors of drilling while maintaining borehole integrity.
