摘要:

碳中和、碳达峰意味着经济和社会领域广泛而深刻的系统变革,未来常规化石能源的利用必然会受到限制。地热能作为一种清洁低碳、稳定连续的非碳基能源,是实现碳达峰、碳中和目标不可或缺的能源。我国油田区存在着大量的沉睡油井,其中的水热型地热资源亟须科学合理的低成本、可持续利用,这将对碳中和的实现有重要意义。综述了油田区沉睡油井改造为地热井的方法,分析了我国油田利用改造后地热井的工程实例,以及油田区开发利用地热能的优势和瓶颈,展望了应用前景,为后续的工程研究提供参考。

Abstract:

Carbon neutrality and carbon peaking will bring extensive and profound systematic transformations to economic and social fields and limits to conventional fossil energy development as well.As a clean,low-carbon,stable and sustainable non-carbon energy,geothermal energy is indispensable to achieve the goal of carbon peak and carbon neutrality. There are a large number of inactive oil wells in China,and some of them are of abundant hydro-geothermal resources expecting to be explore scientifically,economically and sustainably.The exploration will be of great significance to realizing carbon neutrality.By summarizing the transformation ways of inactive oil wells into geothermal wells,and analyzing the existing engineering examples of transformed geothermal wells in China and the advantages and bottlenecks of geothermal energy utilization in oil fields,the application prospect of this transformation is made,which provides a reference for subsequent engineering researches.

Key words: carbon neutrality, carbon peak, oil field, geothermal resources, inactive oil well, engineering application, clean and low-carbon
