Maximizing Core Recovery in Hydraulic Drilling Rigs: Best Practices

Introduction

Core recovery is a crucial factor in geological exploration. A hydraulic drilling rig must be optimized to ensure maximum core sample integrity. This article outlines best practices for enhancing core recovery in exploration coring drill rigs.

1. Proper Selection of Drill Bits

• PDC Bits: Suitable for hard rock formations.
• Diamond Bits: Provide precise cutting and minimal sample disturbance.

2. Optimizing Drilling Parameters

• Controlled Rotation Speed: Prevents core breakage.
• Appropriate Weight on Bit (WOB): Ensures efficient penetration without damaging the sample.
• Maintaining Fluid Circulation: Keeps the borehole clean and stable.

3. Advanced Hydraulic Systems for Core Sampling

• Wireline Core Retrieval: Enhances efficiency in geological core sampling rigs.
• Hydraulic Pressure Adjustment: Allows flexibility in different rock formations.

Conclusion

By following these best practices, portable full-hydraulic core drilling rigs can achieve higher core recovery rates, ensuring accurate geological analysis.
