摘　　要：以文昌13-2综合调整项目采出水为例,在油田现场采用“介质过滤器+陶瓷膜滤器”作为注水系统精细处理设备对低渗油藏进行开采,并观察该工艺过滤效果。现场试验结果表明,过滤效果良好,过滤后水中含油量≤6 mg/L,悬浮物含量≤2 mg/L,悬浮物粒径中值≤1.5μm,可以满足低渗油田注水的水质标准和其他相关规范要求。现场试验采用水反冲洗法进行膜清洗操作,当反冲洗强度为过滤通量的4倍,反冲30 s,清洗效果较好。运行成本主要来自电耗,合计总运行成本为1.186元/m^(3)。The produced water of Wenchang 13-2 comprehensive adjustment project was taken as an example,and "medium filter+ceramic membrane filter" was used as fine treatment equipment of water injection system in oil-field to mine low permeability reservoir,and the filtering effect of this process was observed.Field test results showed that the filtration effect of this method was good;the oil content in the filtered water was less than6 mg/L;the suspended matter was less than 2 mg/L;and the average particle size of suspended matter was less than 1.5 μm.These results showed that this technical scheme could meet the water quality standard of low permeability oil-field injection and other related specifications.In the field test,water backwash method was also used to clean the membrane.The test results showed that when backwash intensity was 4 times of filtration flux and duration of treatment was 30 s,the cleaning effect was satisfied.The operating cost mainly come from power consumption,and the total operating cost was 1.186 yuan/m^(3).
