震击器在XD-X井打捞施工中的应用

Application of Jar Knocker in Fishing Operation in XD-X Well

震击器是一种能产生向上或向下冲击震动的工具,按震击原理可分为液压震击器、机械震击器和自由落体震击器,按震击方向可分为上击器、下击器和双向震击器。XD-X井是一口预探水平井,酸压后管柱卡阻无法起出,使用液压上击器、地面下击器,同时配合使用震击解卡、悬吊解卡等方法,一次性打捞出973.46 m遇卡酸压管柱,为水平井工具卡阻管柱的打捞提供了一种快速有效的打捞方法。

The jar knocker is a tool which can generate a up or down shock movement. It is devided into hydraulic fishing jar,mechanic jar and free-fall jar according to its theory and into top jar,bumper jar and two-way jar according to its jarring direction. XD-X Well is a horizontal well in preliminary exploration. Its string cannot be pulled out after acid fracturing. The hydraulic top jar and surface bumper jar are used with jarring releasing and hanging releasing methods. One-time operation fishes up 973. 46 m stuck acid fracturing string. This is a quick and effective fishing method for fishing up the horizontal well tool which jams the string.
