摘要
本文应用静力等效的方法，对卡瓦式封隔器坐封后，套管的双向应力（环向弯曲应力和轴向弯曲应力）进行了计算，分析了套管内外压差对会管强度的影响，找出了闭式热水循环井套管损坏的原因，并提出预防套管损坏的措施和建议。
Applying the static force equilvalent method, this paper calculates the hoop stress and aalal buck ling force of casing due to the setting of slip supported packer, analyses the effect of pressure difference between the both sides of casing on the casing strength, finds out the cause of casing damage in hot-water closed-cycle wells, and offers the measures and suggestions for the prevention of casing damage
