针对油田生产中大量石油套管发生变形的现状，提出用爆炸胀形法来修复变形的石油套管，建立了该方法的理论计算模型，推导了炸药量的计算公式，并用工程实例验证了公式的正确性。
Aiming at the present situation of deformation of a large number of oil casing in oilfield production, this paper proposes to use an explosion bulge method to repair the deformation of oil casing. The theoretical calculation model of this method is established. The formula of the amount of explosive is deduced. The engineering example is used to verify the formula Correctness
