摘　　要：针对深层气井压裂管柱在高压大砂量条件下的失效问题,应用有限元方法对压裂管柱进行力学分析,得到了应力分布情况,为井下压裂工具的合理设计提供一定的理论依据。In view of the question that the fracturing string in deep gas well is failed on condition of high pressure and much granulated substance, the application of finite element method carries on mechanical analysis to the fracturing string, it obtains the situation of stress distribution, provides certain theory basis for designing the downhole fracturing tool rationally.
