摘　　要：低渗透中高渗油藏进入高含水开发阶段后已形成水驱高渗层段或优势通道,剩余油零散分布,如何提高最终采收率是油藏面临的核心技术瓶颈。微生物活化水驱技术具有低成本、安全环保的优势和扩大波及体积及驱油效率的双重效果,实践表明,该技术改善水驱、降水增油效果显著,提高采收率的发展趋势良好,具有较强的技术适应性和推广应用前景。After entering the high water cut stage, the low permeability and medium high permeability reservoirs have formed the water drive high permeability zone or the dominant channel, the remaining oil is scattered, and how to improve the ultimate recovery is the core technology bottleneck of the reservoirs. The technology of water flooding activated by microorganism has the advantages of low cost, safety and environmental protection, as well as the double effects of enlarging sweep volume and oil displacement efficiency.The development trend of EOR is good, and it has strong technical adaptability and application prospect.
