摘要：

钻井数字孪生技术作为虚拟映射实际钻井过程、实现可视化监测与智能决策的核心手段，成为未来智能钻井发展的必然趋势之一。钻井数字孪生主要涉及地面钻机和地下井筒2方面，前者因研究对象相对稳定且可借鉴的成熟经验较多，国内外已进入系统化研究阶段，但地下井筒因看不见、摸不着、不确定性强、工况复杂程度高、涉及多介质多物理场耦合等问题，其孪生面临巨大挑战。本文围绕钻井数字井筒的构建与应用，系统阐述其核心理论、关键技术与发展趋势，旨在为该领域后续研究与工程实践提供参考。

Abstract:

Drilling digital twin technology, as a core method for virtually mapping actual drilling processes and enabling visual monitoring and intelligent decision-making, has become one of the inevitable trends in the future development of intelligent drilling. Drilling digital twins primarily involve two aspects: surface drilling rigs and subsurface wellbores. While surface rigs have entered systematic research phases globally due to their relatively stable nature and abundant mature experience, subsurface wellbores present significant challenges. These include invisibility, tangibility issues, high uncertainty, complex operating conditions, and the involvement of multi-medium and multi-physics coupling phenomena. This paper systematically elaborates on the core theories, key technologies, and development trends of constructing and applying digital wellbore models for drilling operations. It aims to provide a reference for subsequent research and engineering practice in this field.

Key words: drilling digital wellbore, technology, modeling, data, digital twin
