The rotating liner will impose dragging and carrying force on annulus fluid, leading to the spiral rising of drilling fluid and cement slurry, realizing the fully displacement of cement slurry and achieving higher displacement efficiency.
Technical features
1. Lower the liner string to the design location, and rotate it in case of any encumbrance.
2. Open the pump for circulation to ensure it is in normal operation, and compress balls to realize seat hanging.
3. Hydraulically release, open up ball seats, and then rotate the liner.
4. For cement injection construction, after pressure bumping, propose sending in drill stems.
