Enhancing Core Sample Quality through Borehole Stability Techniques

Introduction

Borehole stability is crucial for obtaining high-quality core samples. This article discusses techniques to improve borehole stability when using exploration coring drill rig, portable full-hydraulic core drilling rig, and geological core sampling rig.

1. Key Challenges in Borehole Stability

• Formation Collapse: Weak zones may cave in, damaging core samples.

• Fluid Loss: Excessive filtration into porous formations can compromise core integrity.

• Mechanical Disturbances: Vibrations and misalignment can affect sample quality.

2. Best Practices for Borehole Stability

• Using Casing Advancements: Supports unstable formations.

• Optimizing Weight on Bit (WOB): Prevents unnecessary disturbances to core samples.

• Maintaining Controlled Fluid Pressure: Reduces borehole collapse risks.

3. Advanced Drilling Technologies

• Portable full-hydraulic core drilling rig: Offers smooth penetration for stable drilling.

• Geological core sampling rig: Designed to maintain formation stability.

• Boring equipment: Enhances borehole precision with minimal deviation.

Conclusion

Proper borehole stabilization techniques ensure high-quality core retrieval. The use of horizontal drilling rig and crawler drill machine further enhances drilling efficiency.
