摘要: 针对海上油田伴生气直接燃烧或排放造成的资源浪费和环境污染问题,开展了海上伴生气处理利用的研究工作。就现有伴生气处理技术、运输方式及接收终端等进行详细介绍和对比,并对伴生气处理方法涉及的关键技术进行梳理,提出了未来海上伴生气处理方法与技术研究领域的研究重点和发展方向。基于海上油田伴生气处理中存在的产量较小、加工外输成本大及就地利用供能不足等特点,提出建造海底伴生气储库,借鉴陆地天然气储气库提出在海上枯竭油气藏改造成伴生气储库的设计流程,建立了海上伴生气储气库的注采气流程。研究中较为详细地论述了伴生气处理的相关技术,并提出建造海底伴生气储库解决海上油田伴生气处理利用问题,研究内容可供同行参考且对保护环境和提高能源利用率具有重要意义。

Abstract: Aiming at the waste of resources and environmental pollution caused by combustion or discharge of associated gas in offshore oilfields, this paper has carried out research work on the treatment and utilization of associated gas in offshore oilfields. In the research, the existing associated gas processing technology, transportation methods, receiving terminal, etc. are introduced and compared in detail, and the key technologies involved in the associated gas processing method are examined, and focus and direction of future researches on the processing method and technology of marine associated gas is proposed. Focus and development direction. Then, considering small output, high processing cost and insufficient energy supply in the treatment of associated gas in offshore oilfields, we propose the construction and design of submarine associated gas storage using offshore oil and gas reservoir, with reference to onshore natural gas storage, and the gas injection and production process of offshore associated gas storage is established. This research discusses the related technology of associated gas treatment in detail, and proposes to build a submarine associated gas storage to solve the problem of associated gas treatment and utilization in offshore oilfields. The research can be referred to by peer researchersand is of great significance for protecting the environment and improving energy efficiency.

Key words: offshore associated gas, LNG, CNG, NGH, gas storage
