- 摘要:
- “三高”油气井尾管回接固井难以保证重叠段固井质量,易发生环空气窜。为了解决固井质量差和环空气窜的技术问题,研制了一种封隔式回接装置,并制定了一套防气窜的尾管回接工艺技术。该技术为解决“三高”油气井尾管固井后气窜难题提供了一种新手段，对尾管回接固井有参考作用。
The "three high" oil and gas well liner tieback cementing technology is difficult to guarantee the cementing quality of overlapping segments, which easily leads to technical issues of annular gas channeling. A new packer tieback device is developed to solve the above issues, making a liner tie-back process to prevent gas channeling. It provides a new technical means for cementing the tail liner of the "three high" oil and gas well, improving the cementing quality of the overlapping section and preventing annulus gas channeling.
