连续油管压井工艺在丘东七井的应用

APPLICATION OF COLIED TUBING KILL TECHNOLOGY IN QIUDONG WELL-7

针对在高压油气井作业中 ,有时会由于某种原因造成用常规方法 (循环法、挤注法、灌注法 )无法完成压井作业的情况 ,通过理论研究出了用连续油管在高压气井中的压井方法 ,将气体的动密封转换成液体的动密封 ,并在吐哈油田丘东七井实施 ,施工一次成功 ,达到了预期的目的 ,创造了经济效益和社会价值。同时为工程技术人员解决类似井的压井提供了好的方法。

During high pressure oil & gas well workover,regular methods can't finish kill operation sometimes(such as circulating method,squeezing method,filling method).A new kill method in high pressure gas well by using colied tubing is studied.It can change dynamic sealing of gas into dynamic sealing of liquid,and it is successfully used in Qiudong well-7.The good economic benefit and social benefit are obtained.It supplies good way of solving same well killing for engineering staff.
