本文介绍了一种新的爆炸修井工艺，对爆炸打通道工艺原理、爆炸整形及爆炸扩径的有关理论进行了分析，通过对油水井套管爆炸扩径中经常发生的几个现象进行计算机模拟计算，提出了爆炸中的药性选择、布药和引爆方式是套管爆炸扩径成败的关键。通过几年来的地面及现场试验，给出了爆炸扩径需药量的计算公式。本文还介绍了与爆炸修井相配套的不密封加固器和密封加固器两种加固工具及其完井技术。 In this paper, a new explosion workover process is introduced. The theory about explosion process, explosion shaping and explosive expansion are analyzed. Several phenomena that often occur in the expansion of oil and water well casing are computerized Simulation calculation, proposed in the explosive choice of medicine, cloth and detonation method is the key to the success or failure of casing explosion. Through the years of ground and field tests, the formula for calculating the amount of explosive expansion required is given. This paper also introduces two kinds of reinforcement tools and their completion technologies, which are unsealed and sealed.
