Integral Spring Centralizer 
the new type integral spring centralizer is made of a piece of steel plate, cutted by laser, and formed by punching, high temperature wire saw welding at last.
1.the Dia of centralizer designed same withwell bore size.
2.no initial resisitance, less friction
3.higher deviationg from the clearance ratio(85%) and better reset force
4.it can attach with the casing tightly in thenecking down string.
5.higher strength, no stress weak points,more reliable. 

 

Turbulent Spring Centralizer
-With the advantages of spring centralizer.
-The spinning disk on the centralizer string can work closely with casing to form a whirl channel to improve the efficency of cement slurry displacment.

SEMI RIGID CENTRALIZER 
Integral rigid structer, mainly used in the process of running casing or cementing which required to rotate the casing. Such as the cementing of shale gas in Sichuan province, it must using this kind of centralizer when running casing which using the CDS top drive.

Preset force Centralizer
-With the advantages of rigid and semi-rigid centralizer, suitable for irregular well bore.
-The centralizer strip can deformed when passing througn the necking down string, it easy to let casing go through.
-The force of centralizer strip can preset according to the requirement of client.

PP Centralizer
PP centralizer with the charactar of low friction, when moving in the downhole with small friction, wear resistance, low torque, low density, rugged, mechanical properties remain stable at -40 ºCto 220 ºC. Polyester polymer material is also highly resistant to corrosion and insulation performance, it is suitable for a variety of complex well conditions.
Hydraulic Centralizer
-Small original OD, big OD after expansion It can significant imporve the centering of casing in horizontal well.
-The ribs can make turbulent flow for the cement grout , greatly improving the quality of cementing.
-The DN is same with casing , with high pressure-bearing ability.
-Designed with anti-return devices, it won't rebound after opening.
-There mounted sets of seals, high reliability.(Patent No.:ZL 201520138274.7)
