Shaanxi Hainaisen Petroleum Technology Co., Ltd. | Drill Bit Application Case: High-Efficiency Drilling in Well Su 25-16-37SX

1. Case Overview

2. Core Drilling Performance Data

3. Project Highlights

3.1 Customized Product Adaptation

Targeting the hard, highly abrasive geological characteristics of the Liujiagou Formation, Shaanxi Hainaisen Petroleum Technology custom-developed the 6-1/SD6522 drill bit (Serial No. A2808) exclusively for this project. We optimized the bit's cutter geometry and wear-resistant PDC material formula to precisely match the formation's drilling requirements, laying a solid foundation for efficient drilling from the source.

3.2 Outstanding Drilling Efficiency

Following standardized construction procedures and supported by Hainaisen's professional on-site technical guidance, the 40607 Drilling Crew achieved a total footage of 2113m in the 707 interval at 2820m well depth, with only 65 hours of net drilling time. The average ROP reached 32.5m/h, representing a 15%-20% improvement over the average ROP of similar intervals in the region. This achievement significantly shortened the construction cycle and reduced overall drilling costs for the client.

3.3 Full-Process Quality Assurance

From factory pre-delivery inspection and on-site installation commissioning to real-time bit wear monitoring and drilling parameter adjustment during operation, Shaanxi Hainaisen Petroleum Technology provided end-to-end technical support throughout the project. This comprehensive service ensured zero failures and zero safety incidents during the entire drilling process, delivering a reliable, worry-free construction experience.

4. Project Value Summary

This case is a typical demonstration of Shaanxi Hainaisen Petroleum Technology's "Customized products + Professional Technical Services" business model. By developing formation-adapted drill bits and implementing refined construction management, we not only achieved high-efficiency drilling in Well Su 25-16-37SX but also verified the reliability and advanced performance of our products in complex formation drilling.

Moving forward, Shaanxi Hainaisen Petroleum Technology will continue to focus on R&D innovation for oil drilling bits, providing high-adaptability, high-efficiency drilling solutions for oil and gas exploration projects worldwide, and helping the global energy industry reduce costs and increase efficiency.
