摘　　要：为提高回注水水质,对PVDF超滤膜在油田采出水处理过程中操作参数的选择及膜污染机理进行了研究,通过现场试验,分析了不同的操作参数对膜通量的影响,超滤膜对含油量及悬浮物的去除效果,膜污染清洗方法。结果表明,超滤膜过滤的优化操作条件为:在确定出水水质达到SY/T 5329-94低渗透油田注水水质A1级标准条件下,温度50℃,浓水回流体积比50%,在线反冲洗周期25 min;NaOH和HNO3联合清洗有助于恢复超滤膜膜通量。In order to improve the injected water quality,the operation parameters and fouling mechanism of ultrafiltration membrane used for treating oilfield produced water were discussed.The field test analyzed the effect of different operation parameter on membrane flux,oil and suspended solid removal efficiency by ultrafiltration membrane,the cleaning method of membrane fouling.Experimental results shown that the optimal operation condition are reflux ratio of 50%,temperature of 50 ℃ and backwash cycle of 25 min when the quality of the effluent is achieved with A1 standard.Results also shown that it is helpful for NaOH combined with HNO3to recover membrane flux.
