碳中和目标下CCUS技术在油田的应用前景

Application Prospect of CCUS Technology in Oilfield under Carbon Neutral Target

实现碳中和是我国的重大战略决策,碳替代、碳减排、碳封存、碳循环是实现碳中和的主要途径。CCUS是通过碳捕集利用与封存达到大规模减少碳排放的技术,是实现碳中和目标的重要技术之一。油田具有良好的源汇匹配基础、完整的注采工程系统和先进的工程技术体系,开展CCUS技术具备明显的优势,油田CO_(2)-EOR是目前最具商业潜力、可大规模碳减排、最有希望工业化应用的CCUS技术。油田拥有大量的特低渗透储量,CCUS技术能够有效开发难采储量,为原油稳产和增产提供支撑。油田碳排放量较大,CCUS技术可以大规模减少碳排放,为实现碳中和目标提供有效途径,对油田开展碳中和路径研究和CCUS应用具有重要的参考意义。

Achieving carbon neutralization is a major strategic decision of China.Carbon substitution,carbon emission reduction,carbon storage,and carbon cycle are the main ways to achieve carbon neutralization.CCUS is a technology to achieve a large-scale reduction of carbon emissions through carbon capture,utilization,and storage,and is one of the important technologies to achieve the goal of carbon neutrality.Oilfields have a good source-sink matching foundation,a complete injection-production engineering system,and an advanced engineering technology system.The development of CCUS in oilfields has obvious advantages.CO_(2)-EOR in oilfield is the CCUS technology with the most commercial potential,large-scale carbon emission reduction and the most promising industrial application.Oilfields have a large number of ultra-low permeability reserves.CCUS technology can effectively develop the reserves which are difficult to recover,and provide support for the stable and increasing production of crude oil.Carbon emissions in oilfields are large,and CCUS technology can reduce carbon emissions on a large scale,providing an effective way to achieve the goal of carbon neutralization.It has important reference significance for the research of carbon neutralization path and the application of CCUS in oilfields.
