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.
