Introduction

Casing centralizer is an important cementing tool to ensure the centering of casing and plays an important role in improving cementing quality. GB/T 19831 "Stone Casing Centralizer for Oil and Natural Gas Industry" is planned to consist of three parts. ---Part 1.Bow spring sleeve centralizer. The purpose is to constrain and standardize the product quality of arcuate spring sleeve centralizers. ---Part 2.Centralizer placement and stop ring testing. The purpose is to determine the installation distance of the centralizer on the casing, in order to achieve The best centralizing effect ensures that the casing is centered. ---Part 3.Rigid and semi-rigid centralizers. The purpose is to constrain and regulate the quality of rigid and semi-rigid centralizer products. This document fully considers the use environment of rigid and semi-rigid centralizers from the well entry process to the completion of cementing, and simulates each use The stress conditions in the environment fully demonstrate the reliability of the product, thereby ensuring the centering of the casing and improving the quality of cementing. Oil and gas industry casing centralizer Part 3.Rigid and semi-rigid centralizers
