Devices Suitable for Sectional Isolation Along Both Cased and Open-hole Wellbores - Geomechanical Packer Formation Model Iteraction

The main goal of this project is to develop an annular isolation system capable to withstand geothermal downhole conditions and mitigate the problems experienced by conventional packers in FORGE wells. This presentation outlines the work in rock modelling and interaction with the annular barrier, as part of the project management and planning phase of the project. More specifically, the lab-scale testing of the scaled annular barrier in rock blocks, as well as modelling and analysis of packer/rock interactions. This presentation focuses on the results of computing stress distribution on the wellbore wall (or casing) and the packer stress and deformation caused by applying high pressure in the interior of the packer.

本项目的核心目标在于研发一种能够承受地热井下环境并缓解传统封堵器在FORGE井中遇到问题的环形隔离系统。本次演讲概述了岩石建模及与环形屏障的相互作用，作为项目管理和规划阶段的工作内容。具体而言，包括在岩石块上对放大比例的环形屏障进行的实验室规模测试，以及封堵器与岩石相互作用建模与分析。本次演讲主要聚焦于计算井筒壁（或套管）上的应力分布以及由封堵器内部施加高压引起的封堵器应力与变形的结果。
