The increasing demand for oil and gas resources, coupled with growing concerns over the environmental impact of conventional chemical agents, has heightened the need for sustainable alternatives. CO responsive materials, which utilize CO as an environmentally friendly stimulus, have emerged as promising solutions for improving chemical performance while minimizing environmental impact in petroleum engineering. This review systematically examines the functional groups, response mechanisms, and synthesis strategies of CO responsive polymers in oil and gas operations, with particular emphasis on their applications in drilling and reservoir engineering. The review explores the relationship between the reversibility of CO responsive materials and their environmental adaptability, focusing on applications in cementing, oil-water separation, gas channeling plugging, viscosity modification, and enhanced oil recovery. By evaluating response mechanisms and environmental adaptability, this work offers valuable insights into the optimization of CO responsive materials for practical use in petroleum operations. Additionally, challenges such as response sensitivity and long-term stability are critically explored, and potential solutions and strategies are proposed. The findings aim to support the low-carbon transformation of the oil industry and promote the adoption of sustainable practices in hydrocarbon extraction.
对石油和天然气资源需求的不断增加，再加上对传统化学剂环境影响的日益担忧，凸显了对可持续替代方案的需求。以一氧化碳（CO）作为环境友好型刺激物的CO响应材料，已成为在石油工程中改善化学性能同时将环境影响降至最低的有前景的解决方案。本综述系统地研究了油气作业中CO响应聚合物的官能团、响应机制和合成策略，特别强调了它们在钻井和油藏工程中的应用。该综述探讨了CO响应材料的可逆性与其环境适应性之间的关系，重点关注其在固井、油水分离、气窜封堵、粘度改性和提高采收率方面的应用。通过评估响应机制和环境适应性，这项工作为优化CO响应材料以实际应用于石油作业提供了有价值的见解。此外，还深入探讨了响应灵敏度和长期稳定性等挑战，并提出了潜在的解决方案和策略。研究结果旨在支持石油行业的低碳转型，并促进在烃类开采中采用可持续做法。
