Rigid roller centralizer
Rigid roller centralizer is a kind of casing centralizer which is widely used for oilfield drilling cementing operation. this kinds of centralizer is especially used in high-angle,high deviated and horizontal well.
Rigid roller centralizer provided by CCSC technology is designed with two kinds of vane structure. One is spiral vane blade structure, another is straight vane blade structure.
Rigid roller centralizer can easy open the well bore thus to improve cementing efficiency.
Roller centralizer not only have all advantages of the ordinary rigid centralizer, but also can turn the Sliding friction into rolling friction.so it will reduce the drag during running casing operation.so it can enhance the safety coefficient when go through complex well section. It is helpful for improving cementing quality and cutting down cost.
Our CCSC rigid roller casing centralizers are available in sizes from 4-1/2" to 20" and suitable for many kinds of casings and wellbore.
Model A Spiral vane blade rigid roller Model B Straight vane blade rigid roller
Features:
●Single piece steel construction, no welding, robust structure
●material include cast steel and cast aluminium
●Available in Straight or Spiral Blade
●Available in Straight or Spiral Configurations
●Easy installation
●Better displacement efficiency of cementing
●Low Friction Between rollers and inside of casing
●Excellent flow area,brilliant mud displacement efficiency in vertical,inclined,horizontal wells.
●High tensile body and good function of corrosion resitance
●Wide vanes distribute load from the casing string into the wellbore without gouging
●Roller centralizer can remove the wellbore stone and improve the mud flow performance
