Industry-Leading Drilling Performance in Liujiagou Formation | 6-1/2SD6522 Drill Bit Case Study

🌍 Case Overview

The Liujiagou Formation is widely recognized in the oil and gas industry for its high rock abrasiveness, hard lithology, and complex geological conditions, which typically lead to low penetration rates, severe bit wear, and frequent bit replacements. Deployed in Well Su 25-13-13X (Well No. 40607), the 6-1/2SD6522 PDC drill bit from Shaanxi Hainaisen Petroleum Technology Co., Ltd. delivered exceptional, record-setting results, overcoming the formation’s challenges and setting a new benchmark for efficient and durable drilling performance.

📋 Detailed Operational Parameters

🔧 Core Technical Advantages

1. 🪨 Customized Design for Abrasive Liujiagou Formation

The 6-1/2SD6522 drill bit is engineered with premium high-wear-resistant PDC cutters and an optimized blade geometry, specifically tailored to combat the extreme abrasiveness and hardness of the Liujiagou Formation. This design maintains sharp cutting edges under prolonged high-pressure drilling, ensuring consistent rock-breaking efficiency without rapid wear degradation.

2. ⚙️ Advanced Hydraulic System for Ultra-High ROP

With an optimized hydraulic flow structure, the bit delivers efficient cutter cooling and rapid rock cuttings evacuation. This eliminates bit balling and maintains a stable 35 m/h mechanical ROP—far exceeding the industry average for the Liujiagou Formation—drastically shortening the overall drilling cycle.

3. 🛡️ Exceptional Durability & Operational Stability

Over 60 hours of continuous pure drilling time and 2096 meters of total footage confirm the bit’s outstanding durability. It completed the entire 694–2790 m well section in a single run, eliminating costly tripping operations and non-productive time (NPT), while minimizing downhole operational risks for the rig team.

💡 Tangible Customer Value Delivered

⏱️ Maximized Time Efficiency: The industry-leading 35 m/h ROP cut well construction time by nearly 40% compared to standard bit performance in the same formation, enabling the client to meet project milestones ahead of schedule and achieve earlier production start-up.

💰 Significant Cost Optimization: Completing the full interval in one run eliminated mid-job bit replacements and reduced tripping frequency, drastically lowering consumable costs, labor expenses, and rig rental fees, directly improving the project’s return on investment (ROI).

🛡️ Enhanced Operational Safety: Stable and reliable performance in highly abrasive geological conditions minimized downhole failure risks, ensuring a smooth, secure, and incident-free drilling process.
