摘　　要：针对吉林油田大安北致密油水平井采用裸眼滑套可开关封隔器多段分压工艺开采,对压后段间矛盾突出,呈现产量低、含水高的情况进行了出水治理技术研究。采用普通油管或连续管带动开关工具,可以将任意层的滑套打开或关闭进行逐层试采,也可以将高含水层段关闭,达到堵水消除段间干扰目的。2口井的现场施工结果表明,施工成功率100%,有效率100%,其中施工后的红平X1井由原来平均日产油0.5 m3增至5.0 m3,红平X2井由原来平均日产油1.8 m3增至8.5 m3。研究结果可为该类水平井的出水治理提供参考。In north Da＇ an, Jilin Oilfield, tight oil is produced by horizontal well, which is completed by switchable openhole sliding sleeve after multistage fracturing. The serious interference between the fractured stages results in low yield with high water-cut. To address the issue, the water control technology is considered. Coiled tubing or conventional tubing can be used to open or close the switchable sliding sleeve at any layer, so as to produce layer by layer, or close the high water-cut layer, thus plugging the water layer and eliminating the layer interference. Application in two wells showed that the success rate of operation is 100% and the effective rate is 100%. After operation, the average daily oil output of Well Hongping XI increased from 0. 5 m3 to 5.0 m3 and Well Hongping X2 increased from 1.8 m3 to 8.5 m3. The research results could provide references for water control in similar horizontal wells.
