本文应用热弹性力学的理论和方法对热力采油井中的套管进行了讨论。指出了单向线膨胀计算套管中的热应力不足之外,并得出了较精确地计算套管中热应力的公式。
In this paper, the theory and method of thermoelasticity are used to discuss casing in thermal oil production wells. The uniaxial thermal expansion in the casing was calculated, and the formula to calculate the thermal stress in the casing more accurately was obtained.
