中国石油网消息：5月11日，从长城钻探钻井一公司传来捷报：由该公司承钻的SN0014-08井顺利完井。该井钻完井周期13.08天，最大位移1400米，成为SN0014平台的钻井新样板，为苏里格致密气高效开发注入强劲动能。
China Oil News: On May 11th, good news came from the First Drilling Company of Changcheng Drilling: The SN0014-08 well, which was drilled by this company, was successfully completed. The drilling and completion cycle of this well was 13.08 days, with a maximum displacement of 1400 meters. It has become a new drilling model for the SN0014 platform, injecting strong impetus for the efficient development of Shurigel tight gas.
此次施工的SN0014平台地处苏里格致密气藏核心区域，面临延长组、刘家沟组地层高漏失、三开裸眼段长、滑动钻进拖压、泥岩地层易坍塌等多重施工挑战。长城钻探坚持创新驱动发展战略，通过理念、技术、机制全维度创新破解施工难题。
The SN0014 platform involved in this construction is located in the core area of the Sulige tight gas reservoir. It faces multiple construction challenges such as high leakage in the Yanchang Formation and Liujiagou Formation, long open-hole sections in the third drilling stage, sliding drilling-induced pressure drag, and the tendency for mudstone formations to collapse. Great Wall Drilling adheres to the innovation-driven development strategy and has successfully solved these construction problems through comprehensive innovation in concepts, technologies, and mechanisms.
长城钻探秉持地质工程一体化理念，全面梳理邻井施工数据，运用大数据分析技术，为该井量身定制“一井一策、一段一法”精细化技术方案；创新采用“五刀翼PDC钻头+大功率螺杆+水力振荡器”高效提速组合，一举攻克滑动钻进拖压、机械钻速偏低等技术难题，钻井效率高达36.49米/小时，大幅压缩了关键工序的施工时间；创新优化钻井液管控体系，以“控密度、降失水、提封堵”专项技术措施有效提升井壁稳定性与井筒清洁度。
Great Wall Drilling adheres to the concept of integrating geological engineering, comprehensively reviews the construction data of adjacent wells, and utilizes big data analysis technology to tailor a "one-well-one-plan, one-section-one-method" refined technical plan for this well. It innovatively adopts a "five-blade PDC drill bit + high-power screw + hydraulic oscillator" efficient speed-up combination, successfully overcoming technical challenges such as sliding drilling drag pressure and low mechanical drilling speed, with a drilling efficiency of up to 36.49 meters per hour, significantly reducing the construction time for key processes. It innovatively optimizes the drilling fluid control system, effectively enhancing wellbore stability and wellbore cleanliness through special technical measures such as "controlling density, reducing water loss, and improving sealing".
同时，公司建立“日分析、日调度、日优化”动态工作机制，技术创新团队全程驻井跟踪，实时优化施工参数，确保施工全程处于精准受控状态。
At the same time, the company has established a dynamic working mechanism of "daily analysis, daily scheduling, and daily optimization". The technical innovation team is stationed at the well site throughout the process to track and optimize the construction parameters in real time, ensuring that the entire construction process is under precise control.
