【Abstract】 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.更多还原
