| 摘 要：以文昌13-2綜合調整項目采出水為例，在油田現場(chǎng)采用“介質(zhì)過(guò)濾器+陶瓷膜濾器”作為注水系統精細處理設備對低滲油藏進(jìn)行開(kāi)采，并觀(guān)察該工藝過(guò)濾效果�，F場(chǎng)試驗結果表明，過(guò)濾效果良好，過(guò)濾后水中含油量≤6 mg/L，懸浮物含量≤2 mg/L，懸浮物粒徑中值≤1.5 μm，可以滿(mǎn)足低滲油田注水的水質(zhì)標準和其他相關(guān)規范要求�，F場(chǎng)試驗采用水反沖洗法進(jìn)行膜清洗操作，當反沖洗強度為過(guò)濾通量的4倍，反沖30 s，清洗效果較好。運行成本主要來(lái)自電耗，合計總運行成本為1.186元/m3。 |

| Abstract：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 than 6 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/m3. |
