A ROTATABLE LINER HANGER WITH EMBEDDED SLIP OF MULTIPLE CONES

The present invention discloses a rotatable liner hanger with embedded slip of multiple cones, wherein: the Cone is separated with Body in order to rotate after setting; the heavy-duty Bearing is designed by slide lubricant, which makes sure that can rotate under overload situation; sealing design of the heavy-duty bearing ensure sealing when rotate; the OD of embedded slip is smaller than that of cone and the slips hide in cone before setting, which can protect slips from collisions in the process of running in the wellbore; every slip's back side contains two inclined surfaces, which makes sure the effect of setting; the slips and cone is connected with inverted cone track, which can protect the slip from scraping; there are six slips that can share the load and reduce damage of the upper casings furthest. Using this device can increase slurry turbulent to improve the cementing quality.
