| 摘 要： | 注水管柱能否靠自重下放到井底是一个十分重要的技术问题。考虑管柱与井壁的初始间隙和随机接触摩擦阻力,建立了注水管柱力分析模型,采用多向接触摩擦间隙元理论对该模型进行了接触非线性力学分析。经大庆油田3口井的计算分析表明,注水管柱最大累计摩阻为0.74 kN,靠管柱自重完全可以下放到井底。

| Abstract: | It is a very important technical question whether water injection string can rely on string weight to go through the well hole or not.Considering the gap and random contact between the string and the well wall,the mechanics analysis model of water injection string is established and nonlinear mechanics analysis is done by using gap element of multi-direction contact and friction theory.The analyzed result of three wells in Daqing Oil Field shows that the maximum cumulative friction of is 0.74 kN.It means th... |
