Current status,bottlenecks and countermeasures for improving oil recovery in shale oil reservoirs
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.
