| 摘 要： | 高效气动套管自动补贴装置由动力部件、运动部件和密封部件3部分组成。装置以火箭固体推进剂燃烧产生的高能气体作动力源,通过动力传动机构将高温、高压气体能转化为机械能,在两端锥锚的相对运动中,使补贴管产生径向扩张而压焊在套管内壁上,达到补贴破损套管的目的。在新疆、中原等油田11口井的成功补贴表明,该装置具有结构简单、可靠性好、操作方便、补贴效果好和成本低等优点,技术性能指标达到设计要求。

| Abstract: | A new automatic casing patch device is developed to meet the need of oilfield casing repairing. The device is comprised of power part, motion part and sealing part. By taking the high-energy gas produced from combustion of the rocket solid propellant as the power source, its power part transfers the high-temperature and high-pressure gas energy into mechanical energy to make the patched casing pressed and welded on the internal wall of the casing through radial expansion. On-site application shows that the device is simple and reliable and easy to operate, and it has good performance. |
