塔河油田部分油井受井底落鱼堵塞油流通道的影响，导致油井严重供液不足，影响产量。运用XJ750 修井机进行打捞落鱼作业受地层坍塌、解卡吨位、落鱼卡钻位置、形态等影响，成功率较低，作业周期长，费用高。提出运用XJ750 修井机绕开原井底落鱼进行打塞、绕障开窗、侧钻加深钻进，从而快速高效恢复油井产能的方法。TH12310 等5 口井的成功实践表明，绕障侧钻技术在塔河油田大修作业中具有较好的应用前景。

Some oil wells of Tahe Oilfield are affected by fish on bottom hole, which blocks oil flow channels, resulting in significantly insufficient supply of fluid to the wells and hence affecting oil production. Fishing job using XJ750 workover rig is affected by formation collapse, stuck freeing tonnage, location of stuck pipe and shape of fish, so the job has low successful rate, long working period and high costs. But if XJ750 workover rig is used to deepen the well by pumping plugs and sidetracking by bypassing obstacles while bypassing the fish at bottom hole, it can recover oil well production quickly and efficiently. Practice has shown that bypassing barrier sidetracking technology enjoys a favorable application prospect in workover jobs in Tahe Oilfield.
