扶余油层属于特低渗透油层,注水开发过程中存在产量低且递减快、注水无法形成有效驱替等问题,为此,提出了二氧化碳驱油的方法,通过研究其增油机理,分析驱油效果的影响因素,评价类似区块的应用效果,探索二氧化碳驱油在扶余油层实施的可行性,为提高扶余油层整体开发效果提供技术支持。

Fuyu oil layer are extremely low permeability reservoir,water injection development process and the presence of low yield diminishing fast,unable to form an effective water displacement and other issues,this paper proposes a method for carbon dioxide flooding,by studying its mechanism of increasing oil production,analyzes the effect of flooding factors to evaluate the effect of a block of similar applications, to explore the feasibility of carbon dioxide flooding in Fuyu oil layer implementation,providing technical support to improve the overall development of Fuyu reservoir effect.
