Description
The liner hanger with packer could seal the annulus between liner and upper casing,and prevent the liquid and the gas from migration.After finishing cementing,set the packer,circulate the excess slurry, and don’t affect the formation under the liner hanger.
When run the liner to the designed depth,set the liner hanger,release the setting tools and finish cementing.After bumping the plug,pull the drill pipe,the claws On the setting tools expand out and act on the upper surface of the polished bore receptacle sleeve,lower down the drill pipe,shear the pins and the rubber sleeves expand to seal the annulus between upper casing and the poilished bore receptacle.
Features
- Design a self—locking rachet ring,set the packer easily and seal the annulus permanently.
- Set the packer with 30-50T load.
- Packer seal capability is 35MPa.
- Rubber could work well under 120 ℃.
- Rubber sleeve has good acid resistant, alkali-resistant and oil resistant properties as well as high temperature resistance.
- Combination of free fall packer and liner hanger, the Liner Hanger with Packer performs double functions – sealing and liner hanging.
- The sealed ram can be pulled out along with running tools, therefore no drill out is required.
