摘要
介绍了页岩油的储量分布、成因及赋存机理,详细概述了页岩油早期勘探、储层改造及后期提采等不同阶段的开发现状.在此基础上,着重综述了当前国内外页岩油藏提高采收率主体技术的应用现状及进展,深入分析了不同页岩油提采技术的优势与不足,同时给出了针对理论认识、技术及经济壁垒的相应策略,最后从不同角度入手,展望了今后页岩EOR的发展前景.
Abstract
This paper introduces the distribution,genesis and occurrence mechanism of shale oil reserves,and summarizes the development status of shale oil in different stages,such as early exploration,reservoir reconstruction and late extraction.On this basis,the current application status and progress of EOR main technologies in shale reservoirs at home and abroad are reviewed,the advantages and disadvantages of different shale oil extraction technologies are deeply analyzed,and the corresponding strategies for theoretical understanding,technical and economic barriers are given.Finally,the development prospects of shale EOR in the future are looked at from different perspectives.
