摘　　要：铁还原菌可以通过改变低渗透油藏中吸水膨胀的蒙脱石结构抑制其水化膨胀,进而改善油藏渗透率,增强注水能力,提高原油采收率,为低渗透油藏的开采提供了一种新思路。分析了低渗透油藏的特点及开采面临的主要问题,介绍了低渗透油藏解堵技术及局限性,综述了铁还原菌提高低渗透油藏采收率的机制及研究进展。Iron-reducing bacteria can inhibit the hydration expansion of montmorillonite by changing the structure of water-absorbing and swelling montmorillonite in low permeability reservoirs,thus improving reservoir permeability,enhancing water injection capacity,and enhancing oil recovery,which provides a new idea for the exploitation of low permeability reservoirs.In this paper,we analyze the characteristics of low permeability reservoirs and the major problems existing in exploitation,introduce the techniques of plugging removal in low permeability reservoirs and their limitations,and summarize the mechanism and research progress in enhancing the oil recovery of low permeability reservoirs by iron-reducing bacteria.

关 键 词：铁还原菌 低渗透油藏 提高采收率 水化膨胀 地层堵塞
