    Abstract:

    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.
