详细介绍
DJ型地面震击器是仅限于在钻井平台上使用,产生向下震击力;井台上实时调节震击吨位,性能可靠,使用方便。出现事故时可迅速安放于钻柱中实现震击作业;对处理键槽卡钻、缩径卡钻和粘吸卡钻事故效果尤为显著。
Surface Bumper Jar Type DJ can be only used on drill platform, producing the downward jarring force. The jarring tonnage should be adjusted momentarily on drill stand for reliable property and usableness. The accidents for key-seating stuck, necked-in stuck and sucking stuck can be handled effectively. It can be mounted on drill string as to realize the jarring operation when accident happened.
