油气井杆管柱的静力稳定性

STATIC STABILITY OF PIPE STRING IN OIL AND GAS WELLS

  • 摘要: 本文建立了斜直井中受压扭细长杆管柱几何非线性屈曲的微分方程,建立了水平井段杆管柱稳定性力学分析的数学模型,导出了斜直井段杆管柱稳定性判别方法,分析了无重杆管柱的几何非线性屈曲。

     

    Abstract: In this paper,buckling formulations of pipe string under compression-torque loading in straight slant wells,and mathematical models for stability analysis of pipe string in horizontal section of wells,and criteria of pipe string buckling station were established and geo-metrically nonlinear buckling of pipe string without weight is analysed.
