摘要

目前，陆上和海上油田的提高采收率（EOR）方法都得到了评价。然而，由于海上油田基础设施、交通设施和地质条件的特殊性，提高采收率的条件更为复杂。从海上天然气EOR （gEOR）试点项目中获得的经验表明，在油田开发的后期阶段，提高石油产量是有效的方法。本文对所获得的技术知识基础进行了分析，其中包括海上项目的优缺点分析以及海上环境中天然气和水气驱的操作经验。介绍了1970年至今海上油田实施的提高采收率项目的历史，并对不同的烃类气体、CO2和氮气注入方法的应用进行了评价。

Gas enhanced oil recovery methods for offshore oilfields: Features, implementation, operational status

Nowadays, enhanced oil recovery (EOR) methods have been evaluated both for onshore and offshore oilfields. However, the conditions for using EOR methods in offshore fields are more complex due to the unique features of the infrastructure, transportation facilities and geological conditions. The experience gained from offshore gas EOR (gEOR) pilot projects has shown effective methods for increasing oil production at a later stage of field development. The technical knowledge base gained has been analyzed in this paper, which includes an analysis of the advantages and disadvantages of offshore projects and operational experience with gas and water-gas flooding in offshore environments. A history of implemented EOR projects in offshore oil fields from 1970 to the present and an evaluation of the application of different injection methods with hydrocarbon gas, CO₂ and nitrogen is presented sequentially.
