Key Features of the Anti-Sticking Drill Bit

1. Innovative Design:

• Features an inverted triangle structure at the bottom for diameter protection, complemented by an internal cutting groove and a blade edge.

• Blade edges are reinforced with PDC teeth or hard aggregate strips for enhanced strength and durability.

2. Diameter Protection Functions:

• Guidance Function: The inverted triangle design enables line contact for diameter maintenance, ensuring smooth discharge of falling blocks along the guide surface to the chip removal groove.

• Crushing Function: Blades effectively cut and discharge large falling blocks via the chip removal slots, minimizing sticking risks.

• Chip Removal Function: Internal chip removal grooves allow for the efficient discharge of hard objects or sand, preventing sticking and ensuring tool safety.

• Reverse Reaming Function: Provides superior reaming capability, extending to the root of the cutting groove, and significantly improving performance in cases of severe diameter reduction.

3. Enhanced Safety and Efficiency:

• Reduces the occurrence of sticking accidents caused by block falling, sand settling, shrinkage, and well leakage.

• Shortens drilling cycles by minimizing handling time for sticking incidents.

Typical Applications

1. Unstable Formations:

• Ideal for formations prone to block falling, sand settling, or shrinkage, where sticking accidents frequently occur.

2. Leak-Prone Zones:

• Provides reliable performance in well leakage scenarios, ensuring smooth operations and tool safety.

3. Severe Diameter Reduction Conditions:

• Effective in reaming and stabilizing boreholes with significant diameter reduction issues.

4. Safety-Critical Drilling Projects:

• A strong guarantee for safe and efficient drilling operations in challenging conditions.

This reorganization clearly separates the drill bit's features from its practical applications, making it easier for potential users to understand its benefits and uses.
