摘要
利用地面震击器是解除井内卡钻事故的有效工具,无论是钻柱的任何部分被卡或卡瓦型的工具和打捞工具被卡,均可使用地面震击器下击解卡,震击器的向下冲击力能通过钻柱传递至卡点,使卡点位置(工具)受到猛烈地向下冲击力,反复震击从而达到解卡的目的。
The use of ground jars is an effective tool to relieve the stuck pipe accident in the well.No matter if any part of the drill string is stuck by a card or a kava-type tool and a salvage tool, The use of jar impact down force can be passed through the drill string to the card point, the card point （tool） by the violent downward impact, repeated shock so as to achieve the purpose of card.
