| 摘 要： | 液动锤套管起拔器的原理是利用冲洗液作为动力介质，推动冲击锤产生振动，将机械应力波通过液动锤传至套管，使其松动后拔起。新研制的液动锤套管起拔器减轻了普通蛮力起拔方法对套管的损伤，节约钻探成本。本文介绍了双作用和正作用两种液动锤套管起拔器的起拔原理以及工作方法，并介绍了其在河北省遵化市西山带铁矿区进行野外试验中取得的效果。

| Abstract: | The principle of the hydraulic hammer casing puller is taking flushing fluid as the power medium to drive the hammer to vibrate and send the mechanical stress wave through the hydraulic hammer to the casing so as to pull it loose and then pull it out. By the newly developed hydraulic hammer casing puller, the damage to casing caused by pulling method of common brute force can be reduced with drilling cost saving. In this paper, the pulling principle and working method of double acting and positive acting hydraulic hammer casing puller are introduced, good results have been achieved in field tests carried out in Zunyi Xishandai iron mine of Hebei Province. |
