靖安油田ZJ2区目前已进入高含水开发阶段,油藏开发表现＂低采出、高含水、递减大＂的特征,油藏平面、剖面矛盾加剧,油藏水驱状况日益复杂,水驱油效率降低,剩余油分布状况日趋复杂,挖潜难度增大,油藏控水稳油形势日益严峻,调驱或三次采油技术储备严重不足。为此,根据低渗透油藏储层特征和流体特征,在广泛调研和室内实验评价的基础上,借鉴东部油田提高采收率的技术思路,开展微生物驱油技术试验,通过矿场实践有效提高了驱油效率和最终采收率,丰富了低渗透油藏提高采收率稳产技术体系,为同类油藏的开发具有重要的战略借鉴意义。

Jingan oilfield ZJ2 area is now in high water cut stage of development, the oil reservoir development performance ＂low recovery, high water cut, decreasing big＂ the characteristic, the oil reservoir plane, section by contradiction, the oil reservoir water flooding situation increasingly complex, the water flooding efficiency is reduced, the remaining oil distribution situation is complicated, increased the difficulty of oil-field, the oil reservoir of water control oil firm is serious, and the flooding or tertiary oil recovery technology reserve seri- ously insufficient. Therefore, according to the characteristics of low permeability oil reser- voirs and fluid characteristics in a wide range of research and indoor experiment based on the assessment of, from the eastern oil field to improve oil recovery technology thinking, and carry out the microbial flooding test technology, through the field practice effectively improved the oil displacement efficiency and the ultimate recovery, rich for low permeability reservoir stable production technology to improve oil recovery system for the development of similar reservoirs is an important strategic significance.
