摘要
用分离变量法和调和函数法分别求解套管温度分布函数和位移函数表达式。根据这些表达式进一步推导套管轴向力和径向力的计算公式,然后根据这些公式定性地分析注蒸汽采油对套管强度的影响。
The expressions of temperature distribution function and displacement function of a easing string by steam flooding are worked out respectively by separate variable method and harmonic function method. By means of these expressions, formulas for calculating the axial and radial forces on the casing are derived and then the influence of steam flooding on casing strength is qualitatively analyzed.
