针对红山嘴油田回注水中硫酸盐还原菌恶性繁殖造成水质恶化的问题，在室内开展对纳滤（NF）和反渗透（RO）等膜过滤工艺的研究，发现两种膜过滤工艺均具有除菌能力。其中，反渗透比纳滤具有更彻底的除菌能力。但由于反渗透膜容易污染，纳滤更易于现场的使用与发展，为弥补纳滤除菌能力的不足，在纳滤除菌的基础上加入化学杀菌剂，进行复合工艺的处理。结果表明，只需少量的化学杀菌剂就能达到完全除菌的目的，既节约了药剂成本，又能避免大量药剂对地层的损害。此工艺具有很好的发展前景。

In order to solve the problem of the deterioration of water quality in oilfield water inj ection sys-tem of Hongshanzui Oilfield which caused by the malignant breeding of sulfate-reducing bacteria,the membrane filtration technologies such as nanofiltration(NF)and reverse osmosis(RO)were studied.Results showed that, these two kinds of membrane filtration technologies could both eliminate bacteria.RO had a greater sterilizing capability than NF.However,NF was selected because of its advantages,for example,it is very easy to use and has better development,while the membrane of RO can be easily contaminated.To consider the lack of NF steri-lizing capability,a chemical bactericide was added on the basis of NF sterilization for complex craft.The results showed that,only a small amount of bactericide could achieve the goal of completely aseptic.This technology saves the cost of reagents and avoids the formation damage by huge amount of reagents,which has a very good prospect.
