- Scope
- This standard mainly sets out requirements for the minimum performance parameters, test procedures and marking methods of arcuate spring sleeve centralizers. These requirements are limited but sufficient to meet the needs of on-site cementing operations. The performance parameters of the bow spring centralizer included in this standard are obtained under specified test procedures. This test method is suitable for: a) Checking and verifying the design, material and process specifications of the manufacturer; b) Regular inspection to ensure the consistency of product performance parameters. This standard does not apply to rigid or solid centralizers. This standard also includes test equipment and marking requirements. In addition, a method for calculating centralizer spacing in inclined vertical wells and dogleg wells based on centralizer performance parameters and deviation clearances is also provided.
