Behind the efficient construction lies the need for a comprehensive guarantee system and the empowerment of cutting-edge technologies. The First Division of Daqing Drilling and Drilling Company adheres to a comprehensive offensive approach and integrated collaboration, establishing a high-standard construction guarantee system. The technical breakthrough team is stationed at the site to provide continuous guidance for the operations. They collaborate with directional wells, drilling fluids and other cooperating units, continuously optimizing construction parameters, strengthening instrument maintenance, and improving the performance of drilling fluids, all to ensure the smoothness of the efficient drilling operations. The equipment asset department implements a refined maintenance system for equipment, conducts comprehensive equipment hazard investigation and rectification, and minimizes non-production operation time to the greatest extent, thereby enhancing the continuity and stability of the construction.

技术创新是提速增效的核心动力。大庆钻探钻井一分公司坚持科技先行、科学施策，施工前结合区块地层特性与施工难点，倒排施工工序、拆解环节工时、量化施工参数，编制科学完善的专项提速方案。施工中精准选配高效钻头、大功率螺杆等专业设备，动态优化钻压、转速等核心参数，大幅提升地层破岩效率。通过实时监测修正井眼数据，保障井眼规整平滑，有效提升复合钻进比例。同时，建立钻井液全天候动态监测机制，根据地层变化实时调整配方，有效防范井塌、井漏等井下风险，守住安全生产底线。

Technological innovation is the core driving force for accelerating progress and improving efficiency. The First Division of Daqing Drilling and Drilling Company adheres to prioritizing technology and implementing scientific strategies. Before the construction, they combined the characteristics of the block strata and the construction difficulties to reverse the construction procedures, break down the working hours of each link, quantify the construction parameters, and formulate a scientific and comprehensive special acceleration plan. During the construction, they precisely selected efficient drilling tools, large-power screws and other professional equipment, dynamically optimized core parameters such as drilling pressure and rotational speed, significantly improving the efficiency of rock breaking in the strata. Through real-time monitoring and correction of wellbore data, they ensured the wellbore was regular and smooth, effectively increasing the proportion of composite drilling. At the same time, they established a 24/7 dynamic monitoring mechanism for drilling fluid, adjusting the formula in real time according to changes in the strata, effectively preventing well-collapse, well-leakage and other downhole risks, and maintaining the bottom-line of safe production.
