能源转型给油井完整性带来了诸多新挑战，而这些挑战在很大程度上仍未被探索和解决。本文从传统视角重新审视油井完整性，并将其与能源转型应用带来的新兴需求进行对比分析。本文整合了各种能源转型应用中常见的油井完整性问题，并基于文献综述和作者丰富的实验室经验，提出了一个统一的视角。文章重点阐述了关键挑战，并提出了未来研究方向，以应对能源转型时代地下作业不断变化的需求。
由于新引入的流体具有独特的性质以及不断发展的作业方式，井筒完整性面临着新的挑战。
氢气（H₂ ）。H₂是自然界中最小的分子，具有很强的渗透性和反应活性。
The energy transition introduces novel challenges to well integrity that remain largely unexplored and unaddressed. In this paper, wellbore integrity from a traditional standpoint is revisited and examined against emerging requirements driven by energy-transition applications. The work consolidates common wellbore-integrity issues across various energy-transition applications, offering a unified perspective based on a literature review and the authors’ extensive laboratory experience. It highlights critical challenges and proposes future research directions to address the evolving needs of subsurface operations in the energy-transition era.
New challenges exist for wellbore integrity because of the unique properties of newly introduced fluids and developing operational aspects.
Hydrogen (H2). H2 is the smallest molecule in nature and is highly penetrative and reactive.
