摘　　要：注水管柱在工作过程中可能会发生蠕动现象,影响了封隔器的使用寿命和注水开发的效果。对坐封后的封隔器进行受力分析,从力学角度探讨了注水管柱蠕动现象产生的机理,为合理设计注水管柱和防止蠕动现象的发生提供了理论依据。以管柱力学分析为基础,提出了注水管柱蠕动量计算的方法,并进行了实例计算,研究成果对准确分析注水管柱力学性能、优化施工工艺参数、提高注水作业有效期有重要意义。Injection string may creep during the working,which may affect the service life of packer and the effect of water injection. Analyzing the force of sealed packer and discussing the mechanism of injection string creeping from the view of mechanics provided a theoretical basis for designing injection string and preventing creeping. On the basis of string mechanics,a calculation method on displacement of string creeping was proposed,and a calculation example was given. The research has important significance on analyzing mechanical properties of injection string accurately,optimizing the processing parameters and improving the useful life of injection string.
