摘　　要：油气田开发中后期生产过程中,油管砂埋、砂卡现象多发。为准确高效解卡,并最大限度地减少油管遇卡造成的损失,研制井下油管内切割装置。该装置通过电动系统驱动;利用锚爪和扶正器固定在油管内壁;步进电机带动滚珠丝杠转动,圆锥体逐步向外推出刀具至与被割油管内壁接触;电动马达带动刀具高速旋转,从内部切割油管。室内测试结果表明:该装置可准确高效地完成油管切割,切割后刀齿完整性好,油管切口平整、光滑,作业效果良好;操作简单、自动化程度高,为处理遇卡油管提供新思路,具有较好的应用前景。In the middle and later stage of oil and gas field development,the phenomenon of tubing sand burial and sand sticking occurs frequently.In order to realize accurate and efficient unblocking and minimize the loss caused by tubing jamming,a downhole tubing inner cutting device is developed.The device is driven by an electric system;The anchor claw and centralizer are used to fix it on the inner wall of the oil pipe;The stepping motor drives the ball screw to rotate,and the cone gradually pushes out the tool to contact the inner wall of the cut pipe;The electric motor drives the cutter to rotate at high speed to cut the oil pipe from the inside.The indoor test results show that the device can complete the cutting accurately and efficiently,the integrity of the cutter teeth after cutting is good,the oil pipe incision is flat and smooth,and the operation effect is good;The operation is simple and the degree of automation is high,which provides a new idea for dealing with stuck tubing and has a good application prospect.
