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。
According to the multi-section partial pressure technology of open-air packer in the open pit horizontal well of Daanbei tight oil horizontal well in Jilin Oilfield, the contradiction between the pressure back-end section is outstanding, and the research on effluent treatment technology is carried out with low output and high water content. Using ordinary tubing or continuous tube driven switch tools, you can open or close any layer of the sleeve to test the layer by layer, you can also close the aquifer section, to block the water to eliminate the purpose of interference between sections. The results of on-site construction of 2 wells showed that the construction success rate was 100% and the effective rate was 100%. After the construction, the Hongping X1 well increased from 0.5 m3 to 5.0 m3. The average horizontal well X2 from the original average of 1.8 m3 to 8.5 m3. The results can provide reference for the treatment of effluent from horizontal wells.
