Abstract:For settling the technology difficulty of cementing in deep wells and improve deep-well cementing quality,the rotating-casing cementing technique can be applied in these wells.This file analyzes the principlen of improving mud displacement efficiency by rotating casing,presents themechanism of liner hangers and advantages of this cementing tachnique,and proposes the required conditions and precautions for this technique.its application in CB306 well is introduced.the cementing practice indicates that employing this cementing technique can not only tackle technical problems resulted from slim annulus of liners but also improve cementing qualty in deep wells.
Keywords:rotating-casing  CB-306 well  liner cementing  displacement efficency  cement quality
