  Solid Steel Body Rigid Centralizers Applied in Centralizing Casing

  The necessary procedure of drilling well for production task is to install the casing in the well to line the borehole and then the space between exterior of casing and inside of borehole is filled with cement.The important point is that the casing must be centralized in the wellbore when cement job,so the solid steel body rigid centralizers act as cementing tool is launched to hold the casing away from the well bore and towards the centre of the bore.

  Supplying Bow Rigid Centralizer For Primary Cement Job

  The feature of bow rigid centralizer is flat bottom U profile of different depths,the flat botton U profile is also rib design whose feature of bow rigid centralizer allows for optimized fluid flow in the annulus.At the same time the U profile provides better standoff for more effective centralization than standard bow spring centralizer.

  How To Improve The Cementing By Solid Rigid Centralizer

  The solid rigid centralizer is one kinds of casing centralizer that achieves obvious cementing quality like reducing the drilling and completion costs and time. Solid rigid centralizer provides the positive standoff tool when casing running in the wellbore,making casing keep off the wellbore to get cement all around.

  Composite Rigid Centralizer Manufacturing Process and Performance Test

  The composite rigid centralizer is designed for high friction and temperature horizontal well. Because the rigid centralizer is made of high quality composite material like nylon and fiber glass whose features are low frition,heat resistant and highly durable. The max operating temperature of composite rigid centralizer is 200°C.

  Performance Test of Casing Centralizer

  In order to have favourable and sucessful cementing effect,casing centralizer must be tested according to API 10D standard,bow spring casing centralizer which is basically designed for vertical wells where low starting forces and high restoring forces are required.

  Casing Centralizer Selection and Installation

  The profect centralization is very important for completing high quality cementing operation. The engineers from Puyang Zhongshi Group provide more than just casing centralizers, they provide service of selecting and installating casing centralizers. What they do is to minimize the compromise between getting casing to bottom and achieving good zonal isolation.

  What is Rigid Centralizer

  Rigid centralizers are used for casing centralization in cementing operation, the solid body of rigid centralizer is made of casting steel, aluminum,aluminum alloy or zinc alloy,reducing torque and drag, increasing flowing-by in the wellbore.
