Hebei Shangshan Petroleum Machinery Co., Ltd. and Beijing University of Technology have jointly carried out technical research on the high-torque multi-stage impeller hydraulic rotating guide shoe. Leveraging the respective strengths of both parties in engineering manufacturing, fluid mechanics and structural optimization, the research targets the bottlenecks of casing running and cementing operations under complex well conditions to develop a new generation of high-efficiency, reliable, high-temperature and high-pressure downhole steering tools, so as to improve the quality and efficiency of oil and gas exploration and development.
This cooperation is based on the technical development contract for structural design and optimization research of hydraulic rotating guide shoes signed by both parties. The project runs from June to August 2025. The research team of Beijing University of Technology is responsible for overall structural design, strength verification and parameter optimization of key components, while Hebei Shangshan Petroleum Machinery provides field working condition requirements, technical standards and industrialization support, forming a full-chain industry-university-research closed loop of "demand – R&D – verification – commercialization".
Focus on Industry Pain Points to Solve Operational Challenges in Complex Wells
As oil and gas development extends to deep, unconventional, large-displacement and horizontal wells, frequent problems such as borehole diameter shrinkage, sand bridge accumulation and step obstructions occur. Conventional fixed guide shoes are prone to difficulties in running casing and unstable cementing quality. The jointly developed high-torque multi-stage impeller hydraulic rotating guide shoe is powered by drilling fluid, generating stable rotating torque through the multi-stage impeller structure. Integrating multiple functions including rotary steering, wall scraping and reaming, sand cleaning and cuttings carrying, and turbulent cementing, it can efficiently pass through complex well sections, greatly reduce the risk of sticking, and improve casing running efficiency and cementing qualification rate.
Core Technical Indicators Benchmarking High-End Downhole Tools
High temperature resistance: Stable continuous operation at 150℃
Torque: 400 N·m
Starting performance: Flow pressure differential of 0.3 MPa
Structural advantages: Multi-stage impeller delivers more stable torque output. The eccentric steering head combined with cemented carbide scraping structure is suitable for deep wells, ultra-deep wells and complex structural wells.
Hebei Shangshan Petroleum Machinery Co., Ltd. specializes in the R&D and manufacturing of petroleum machinery, boasting a mature manufacturing system and solid market reputation in the fields of casing accessories and downhole tools. Beijing University of Technology has profound academic and technical accumulation in mechanical structural strength analysis and fluid machinery simulation and optimization, providing solid theoretical and technical support for the project.
Taking this cooperation as an opportunity, both parties will further deepen industry-university-research collaboration, promote the localization substitution of high-end drilling tools, deliver more reliable equipment support for the safe and efficient development of oil and gas fields, and facilitate the high-end, intelligent and localized development of China’s petroleum equipment industry.
