摘　　要：为了提高不压井修井作业时油管内封堵的可靠性,针对低压油水井的作业需求,设计出新型的不压井防喷吊卡。该机构是将油管内封堵位置调整到井口,在油管接箍卸扣处进行动态密封。应用三维软件建立吊卡模型,导入流体仿真软件及运动仿真软件进行分析,获得了吊卡的力学和动力学数据。结果表明该机构安全、稳定。为现场使用提供了理论支持,为进一步改进防喷吊卡提供了参考依据。A design of new plugging elevator was put forward to meet the functional requirements of low pressure snubbing workover system. This tool can seal the tube at wellhead during the tubing breakout process. The results of stress analysis and dynamics simulation show the performance of this tool is safe and stable. The result provides theoretical support for field test and for ward research.
