Product Description

DHD360/SD6/QL6 Overburden Eccentric Casing Drilling System Bit for Rock Formation

Product Description

Down the hole (DTH) tools manufacturer KINGDRILLING Head Eccentric Casing drilling system is made up of a pair of chain embedded 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 type is especially suitable for 114-273mm in diameter.

Functions of Overburden Casing Drilling System:

The Overburden Casing Drilling system performs several critical functions that contribute to its efficiency and effectiveness in drilling operations:

1. Simultaneous Casing Advancement and Drilling: The OCD system allows for the simultaneous advancement of casing and drilling, eliminating the need to pull out the drill string for casing installation. This continuous operation reduces downtime and improves workflow efficiency.

2. Reaming and Enlarging Borehole: The system incorporates reaming shells that help enlarge the borehole diameter as the casing is advanced through challenging formations. This function ensures proper casing fit and borehole stability.

3. Cuttings Removal and Fluid Circulation: The drilling fluid circulation system in the OCD system serves to carry cuttings to the surface, cool the drill bit, and provide lubrication for smooth drilling operations. This function is essential for maintaining drilling efficiency and equipment longevity.

4. Casing Protection and Integrity: Specialized casing shoes and design features protect the casing from wear and damage during drilling. These components ensure the integrity of the casing string and contribute to the overall success of the drilling operation.
