Abstract

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
