摘　　要：现有套管补贴技术存在通径小的缺陷,燃气动力大通径补贴技术能够解决这一问题。通过设计包含燃气动力装置、气流转换装置、锚定装置、扩径装置的系统装置来实现补贴目的,补贴后通径可达到原套管内通径的90%以上,能够满足现有注采设备通过的要求,地面实验验证了设计合理性。The finished passage of existing casing patching technology is all deficient,and the propellant powered big passage patching device can solve the problem.The designed system device including propellant powered assembly,gas diversion assembly,anchor-hold assembly,radial-expanding assembly etc.achieves the patching aim.The finished passage after patching is upwards of 90% of the original casing.The rationality of this device was approved by the tests.
