Bow Spring Casing Centralizer Mechanical Performance Analysis And Design

The purpose of a casing centralizer is to facilitate running casing to the desired depth and to assist in centering the casing in the well bore.One of the main objectives of centrailizing a casing string is to facilitate a good cementing,thereby isolating fluids from different zonges.A bow-spring centralizer can be constructed in various ways,using various types,shapes and quantities of bow spring.Based on the cementing process, analysis of the bow spring casing centralizers role in the cementing process, thus, a reasonable mechanical model, based on the structural model of the centralizer analysis to identify the location and improvement of the weak Components, while the product according to the mathematical model to calculate the mechanical data, according to the structure of the mechanical data to improve products, to improve the mechanical properties, and enhance product quality, rational use of raw materials, while mathematical model can for the next product innovation Provide a theoretical basisIn this paper, Bow spring casing centralizers Mechanical Properties for product innovation and rational use of raw materials to provide a reliable theoretical basis, thus ensuring product quality and mechanical properties and conditions, the more rational use of resources and products to save energy increase efficiency lay a solid theoretical basis.
