微生物采油技术在子长油田的应用
Xi'an Shiyou Daxue Xuebao (Ziran Kexue Ban)/Journal of Xi'an Shiyou University, Natural Sciences Edition（2010）
Abstract
为了提高子长油田降沟区块的产量和采收率,从微生物采油机理和适用条件入手,通过室内模拟实验和现场试验考察其可行性.结果表明,在温度40℃、矿化度5×103mg/L的油藏条件下,注入茵液质量分数为2%～5%的M1系列、M2系列茵组后增油效果明显,可以提高采收率10%,投入产出比为1:11.2.现场应用效果表明,在子长油田降沟区长2区块实施微生物驱油技术是可行的.
