Research on Packer Material Stress Analysis

摘要

Stress conditions of downhole packer are more complicated. Based on the packer structure and the environment the metal material exposes, this paper establishes proper numerical simulation model. And ANSYS software is utilized to carry out finite element analysis of built-up model to obtain stress distribution of metal material. On the basis of stress evaluation of metal material, stress of specific metal parts is analyzed and conformity of packer is determined. Furthermore, corresponding optimization is performed based on the results of stress analysis, which provides theoretical reference for the future structural design of packer.
