Abstract

Abstract: Wellbore integrity is a key factor to ensuring the safe and sustainable operation of oil and gas wells throughout the life cycle. As the global energy exploitation expands to regions with deep formations，deep seas and complex geological conditions，the wellbore barrier system is facing unprecedented challenges due to extreme conditions such as high temperature and high pressure （HTHP），high stresses and corrosive media. Over recent years，great progress has been made in research on wellbore integrity thanks to the development of new materials，applications of intelligent monitoring techniques and innovation of risk assessment models. This paper summarizes the research status of multiple aspects of wellbore integrity，such as HTHP-tolerant materials，composite materials resistant to hydrogen penetration，smart sensors and data-driven prediction models，and multi-factor risk assessment methods. Moreover，it reviews the current challenges in long-term durability validation of materials，reliability of intelligent monitoring systems and applicability of multi-scale models as well as special requirements of emerging application scenarios for Carbon Neutrality. This paper provides references for safe development of oil and gas and integrity management of subsurface storage and transportation facilities for energy transformation.

Key words: wellbore integrity, wellbore materials, intelligent monitoring, risk assessment, development direction

摘要： 井筒完整性是确保油气井在整个生命周期内安全和可持续运营的关键因素。随着全球能源开发向深地、深海及复杂地质条件区域拓展，高温高压、高应力及腐蚀性介质等极端条件对井筒屏障系统提出了前所未有的挑战。近年来，新材料的发展、智能监测技术的应用和风险评估模型的创新，推动井筒完整性研究在材料性能提升、监测与预测智能化以及失效风险管理等方面取得了显著进展。围绕耐高温高压材料、抗氢渗透复合材料、智能传感器与大数据预测模型，以及多因素风险评估方法等方面的研究现状，探讨了当前面临的材料长期耐久性验证、智能监测系统可靠性、多尺度模型适用性等技术挑战，以及面向碳中和背景下新兴应用场景带来的特殊要求。该成果可为油气安全开发及能源转型中的地下储运设施完整性管理提供参考。
