摘要:
连续油管钻磨作业过程中，需反复拖动钻磨工具串完成井筒的冲洗，施工时间长、效率低。在连续油管钻磨工具组合中增加飓风冲洗工具，可提高冲洗阶段排量至设计值以上，清理井筒内大直径固相颗粒，提升了井筒清理效率。通过室内实验及现场试验效果评价，当排量高于500 L/min时，飓风冲洗工具完全开启，马达因液体分流未受损伤，清理井筒排量得到进一步提升，平均钻磨用时减少331%，平均清理井筒用时减少749%，平均施工用时减少527%；而当排量低于400 L/min时，飓风冲洗工具完全关闭。飓风冲洗工具可在确保配套连续油管、井口装置、井筒本质安全的前提下，提升钻磨整体施工效率。
Abstract:
 During the coiled tubing (CT) drilling and grinding operations, the drilling and grinding tool string needs to be dragged repeatedly to flush the wellbore, which is timeconsuming and inefficient. Adding hurricane flushing tool to the CT drilling and grinding tool string can increase the displacement in the flushing stage above the design value to clean out largediameter solid particles in the wellbore, so that the wellbore cleaning efficiency is improved. The results of indoor and field tests show that when the displacement is higher than 500 L/min, the hurricane flushing tool is fully turned on, the motor is not damaged due to liquid diversion, and the displacement for wellbore cleaning is further improved; meanwhile, the average drilling and grinding time is reduced by 331%, the average wellbore cleaning time is reduced by 749%, and the average operation time is reduced by 527%. When the displacement is lower than 400 L/min, the hurricane flushing tool is completely closed. The hurricane flushing tool can help improve the overall efficiency of drilling and grinding while ensuring the intrinsic safety of supporting CT, wellhead devices and wellbore.
